• Build associative array based on values of another associative array

  - by macek

  I'm looking for an elegant way to turn this array: Array ( [foo] => 1 [bar] => 1 [zim] => 3 [dib] => 6 [gir] => 1 [gaz] => 3 ) Into this array: Array ( [1] => Array ( foo, bar, gir ), [3] => Array ( zim, gaz ), [6] => Array ( dib ) ) Note:, there is no relationship between the keys or values. They are completely arbitrary and used as examples only. The resulting array should be an associative array grouped by the values of the input array. Thanks!

• How to pass an associative array as argument to a function in Bash?

  - by niksfirefly

  How do you pass an associative array as an argument to a function? Is this possible in Bash? The code below is not working as expected: function iterateArray { local ADATA="${@}" # associative array for key in "${!ADATA[@]}" do echo "key - ${key}" echo "value: ${ADATA[$key]}" done } Passing associative arrays to a function like normal arrays does not work: iterateArray "$A_DATA" or iterateArray "$A_DATA[@]"

• jQuery - change a list of elements to an associative array

  - by Brian M. Hunt

  Given an associative array (of the sort returned by jQuery.serializeArray()) like this: [ { 'name': 'abc', 'value': 'aaa', '__proto__': [Object] }, { 'name': 'def', 'value': 'bbb', '__proto__': [Object] }, { 'name': 'abc', 'value': 'ccc', '__proto__': [Object] } ] How can one convert this, using either jQuery or just javascript, to an associative array of name: [values] like this: { 'abc': ['aaa', 'ccc'], 'def': ['bbb'] } This seems to essentially be the inverse of this question: Build associative array based on values of another associative array... but in Javascript (not PHP). I wasn't able to find this question on Stackoverflow, though I thought it would have been asked. Thank you for reading. Brian

• Bash scripting - Iterating through "variable" variable names for a list of associative arrays

  - by user1550254

  I've got a variable list of associative arrays that I want to iterate through and retrieve their key/value pairs. I iterate through a single associative array by listing all its keys and getting the values, ie. for key in "${!queue1[@]}" do echo "key : $key" echo "value : ${queue1[$key]}" done The tricky part is that the names of the associative arrays are variable variables, e.g. given count = 5, the associative arrays would be named queue1, queue2, queue3, queue4, queue5. I'm trying to replace the sequence above based on a count, but so far every combination of parentheses and eval has not yielded much more then bad substitution errors. e.g below: for count in {1,2,3,4,5} do for key in "${!queue${count}[@]}" do echo "key : $key" echo "value : ${queue${count}[$key]}" done done Help would be very much appreciated!

• Double associative array or indexed + associative array

  - by clover

  I'm undecided what's the best-practice approach for what I'm trying to do. I'm trying to enter data into an array where the data will look like this: apple color: red price: 2 orange color: orange price: 3 banana color: yellow price: 2 pineapple color: yellow price: 5 When I get input, let's say green apple (notice it's a combo of color + name of fruit), I'm going to check if the name of fruit part exists in the array and display its data (if it exists). What's the right way to compose those arrays? How would I do an indexed array containing an associative array? (or would this be better as 2 nested associative arrays, I'm guessing not)

• PL/SQL bulk collect into associative array with sparse key

  - by Dan

  I want to execute a SQL query inside PL/SQL and populate the results into an associative array, where one of the columns in the SQL becomes the key in the associative array. For example, say I have a table Person with columns PERSON_ID INTEGER PRIMARY KEY PERSON_NAME VARCHAR2(50) ...and values like: PERSON_ID | PERSON_NAME ------------------------ 6 | Alice 15 | Bob 1234 | Carol I want to bulk collect this table into a TABLE OF VARCHAR2(50) INDEX BY INTEGER such that the key 6 in this associative array has the value Alice and so on. Can this be done in PL/SQL? If so, how?

• Converting a PHP associative array to a JSON associative array

  - by Extrakun

  I am converting a look-up table in PHP which looks like this to JavaScript using json_encode: AbilitiesLookup Object ( [abilities:private] => Array ( [1] => Ability_MeleeAttack Object ( [abilityid:protected] => [range:protected] => 1 [name:protected] => MeleeAttack [ability_identifier:protected] => MeleeAttack [aoe_row:protected] => 1 [aoe_col:protected] => 1 [aoe_shape:protected] => [cooldown:protected] => 0 [focusCost:protected] => 0 [possibleFactions:protected] => 2 [abilityDesc:protected] => Basic Attack ) .....snipped... And in JSON, it is: {"1":{"name":"MeleeAttack","fof":"2","range":"1","aoe":[null,"1","1"],"fp":"0","image":"dummy.jpg"},.... The problem is I get a JS object, not an array, and the identifier is a number. I see 2 ways around this problem - either find a way to access the JSON using a number (which I do not know how) or make it such that json_encode (or some other custom encoding functions) can give a JavaScript associative array. (Yes, I am rather lacking in my JavaScript department). Note: The JSON output doesn't match the array - this is because I do a manual json encoding for each element in the subscript, before pushing it onto an array (with the index as the key), then using json_encode on it. To be clear, the number are not sequential because it's an associative array (which is why the JSON output is not an array).

• Return an Oracle Associative Array from a function

  - by Paul Johnson

  Does anybody know if it is possible to return an associative array as the result of an Oracle function, if so do you have any examples? I have an Oracle package which contains an associative array declaration as defined below: TYPE EVENTPARAM IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; This is then used in a stored procedure outside the package as follows: v_CompParams areva_interface.eventparam; The intention is to store an associative array of strings in the variable v_CompParams, returned from a Parse function in another package. The definition for which is as follows: PACKAGE STRING_MANIP IS TYPE a_array IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; FUNCTION Parse (v_string VARCHAR2, v_delim VARCHAR2) RETURN a_array; FUNCTION RowCount(colln IN a_array) RETURN NUMBER; END; The code which implements this is: v_CompParams := STRING_MANIP.PARSE(v_CompID,v_Delim); Unfortunately it doesn't work, I get the error 'PLS-00382: expression is of wrong type'. I foolishly assumed, that since a_array derives from the same source Oracle type as the variable v_CompParams, that there would be no problem casting between them. Any help much appreciated. Kind Regards Paul J.

• Variables versus constants versus associative arrays in PHP

  - by susmits

  I'm working on a small project, and need to implement internationalization support somehow. I am thinking along the lines of using constants to define a lot of symbols for text in one file, which could be included subsequently. However, I'm not sure if using variables is faster, or if I can get away with using associative arrays without too much of a performance hit. What's better for defining constant values in PHP, performance-wise -- constants defined using define("FOO", "..."), or simple variables like $foo = "...", or associative arrays like $symbols["FOO"]?

• Nested foreach loops for associative array combinations

  - by JohnL

  I have an associative array as follows: $myarray = array('a'=>array(), 'b'=>array(), 'c'=>array(), 'd'=>array()); I want to be able to get all pairs of elements in the array. If it wasn't an associative array, I would use nested for loops, like: for($i=0; $i<count($myarray); $i++) { for($j=$i+1; $j<count($myarray); $j++) { do_something($myarray[$i], $myarray[$j]); } } I have looked at using foreach loops, but as the inner loop goes through ALL elements, some pairs are repeated. Is there a way to do this? Thanks!

• array_splice() - Numerical Offsets of Associative Arrays

  - by Alix Axel

  I'm trying to do something but I can't find any solution, I'm also having some trouble putting it into works so here is a sample code, maybe it'll be enough to demonstrate what I'm aiming for: $input = array ( 'who' => 'me', 'what' => 'car', 'more' => 'car', 'when' => 'today', ); Now, I want to use array_splice() to remove (and return) one element from the array: $spliced = key(array_splice($input, 2, 1)); // I'm only interested in the key... The above will remove and return 1 element (third argument) from $input (first argument), at offset 2 (second argument), so $spliced will hold the value more. I'll be iterating over $input with a foreach loop, I know the key to be spliced but the problem is I don't know its numerical offset and since array_splice only accepts integers I don't know what to do. A very dull example: $result = array(); foreach ($input as $key => $value) { if ($key == 'more') { // Remove the index "more" from $input and add it to $result. $result[] = key(array_splice($input, 2 /* How do I know its 2? */, 1)); } } I first though of using array_search() but it's pointless since it'll return the associative index.... How do I determine the numerical offset of a associative index?

• How to write a good PHP database insert using an associative array

  - by Tom

  In PHP, I want to insert into a database using data contained in a associative array of field/value pairs. Example: $_fields = array('field1'=>'value1','field2'=>'value2','field3'=>'value3'); The resulting SQL insert should look as follows: INSERT INTO table (field1,field2,field3) VALUES ('value1','value2','value3'); I have come up with the following PHP one-liner: mysql_query("INSERT INTO table (".implode(',',array_keys($_fields)).") VALUES (".implode(',',array_values($_fields)).")"); It separates the keys and values of the the associative array and implodes to generate a comma-separated string . The problem is that it does not escape or quote the values that were inserted into the database. To illustrate the danger, Imagine if $_fields contained the following: $_fields = array('field1'=>"naustyvalue); drop table members; --"); The following SQL would be generated: INSERT INTO table (field1) VALUES (naustyvalue); drop table members; --; Luckily, multiple queries are not supported, nevertheless quoting and escaping are essential to prevent SQL injection vulnerabilities. How do you write your PHP Mysql Inserts? Note: PDO or mysqli prepared queries aren't currently an option for me because the codebase already uses mysql extensively - a change is planned but it'd take alot of resources to convert?

• sort associative array in awk - help?

  - by Richard

  Hi all, I have an associative array in awk that gets populated like this... chr_count[$3]++ When I try to print my chr_counts I use this: for (i in chr_count) { print i,":",chr_count[i]; } But not surprisingly, the order of i is not sorted in any way. Is there an easy way to iterate over the sorted "keys" of chr_count?

• Google Chrome: JavaScript associative arrays, evaluated out of sequence

  - by Jerry

  Ok, so on a web page, I've got a JavaScript object which I'm using as an associative array. This exists statically in a script block when the page loads: var salesWeeks = { "200911" : ["11 / 2009", "Fiscal 2009"], "200910" : ["10 / 2009", "Fiscal 2009"], "200909" : ["09 / 2009", "Fiscal 2009"], "200908" : ["08 / 2009", "Fiscal 2009"], "200907" : ["07 / 2009", "Fiscal 2009"], "200906" : ["06 / 2009", "Fiscal 2009"], "200905" : ["05 / 2009", "Fiscal 2009"], "200904" : ["04 / 2009", "Fiscal 2009"], "200903" : ["03 / 2009", "Fiscal 2009"], "200902" : ["02 / 2009", "Fiscal 2009"], "200901" : ["01 / 2009", "Fiscal 2009"], "200852" : ["52 / 2008", "Fiscal 2009"], "200851" : ["51 / 2008", "Fiscal 2009"] }; The order of the key/value pairs is intentional, as I'm turning the object into an HTML select box such as this: <select id="ddl_sw" name="ddl_sw"> <option value="">== SELECT WEEK ==</option> <option value="200911">11 / 2009 (Fiscal 2009)</option> <option value="200910">10 / 2009 (Fiscal 2009)</option> <option value="200909">09 / 2009 (Fiscal 2009)</option> <option value="200908">08 / 2009 (Fiscal 2009)</option> <option value="200907">07 / 2009 (Fiscal 2009)</option> <option value="200906">06 / 2009 (Fiscal 2009)</option> <option value="200905">05 / 2009 (Fiscal 2009)</option> <option value="200904">04 / 2009 (Fiscal 2009)</option> <option value="200903">03 / 2009 (Fiscal 2009)</option> <option value="200902">02 / 2009 (Fiscal 2009)</option> <option value="200901">01 / 2009 (Fiscal 2009)</option> <option value="200852">52 / 2008 (Fiscal 2009)</option> <option value="200851">51 / 2008 (Fiscal 2009)</option> </select> ...with code that looks like this (snipped from a function): var arr = []; arr.push( "<select id=\"ddl_sw\" name=\"ddl_sw\">" + "<option value=\"\">== SELECT WEEK ==</option>" ); for(var key in salesWeeks) { arr.push( "<option value=\"" + key + "\">" + salesWeeks[key][0] + " (" + salesWeeks[key][1] + ")" + "<\/option>" ); } arr.push("<\/select>"); return arr.join(""); This all works fine in IE, FireFox and Opera. However in Chrome, the order comes out all weird: <select id="ddl_sw" name="ddl_sw"> <option value="">== SELECT WEEK ==</option> <option value="200852">52 / 2008 (Fiscal 2009)</option> <option value="200908">08 / 2009 (Fiscal 2009)</option> <option value="200906">06 / 2009 (Fiscal 2009)</option> <option value="200902">02 / 2009 (Fiscal 2009)</option> <option value="200907">07 / 2009 (Fiscal 2009)</option> <option value="200904">04 / 2009 (Fiscal 2009)</option> <option value="200909">09 / 2009 (Fiscal 2009)</option> <option value="200903">03 / 2009 (Fiscal 2009)</option> <option value="200905">05 / 2009 (Fiscal 2009)</option> <option value="200901">01 / 2009 (Fiscal 2009)</option> <option value="200910">10 / 2009 (Fiscal 2009)</option> <option value="200911">11 / 2009 (Fiscal 2009)</option> <option value="200851">51 / 2008 (Fiscal 2009)</option> </select> NOTE: This order, though weird, does not change on subsequent refreshes. It's always in this order. So, what is Chrome doing? Some optimization in how it processes the loop? In the first place, am I wrong to rely on the order that the key/value pairs are declared in any associative array? I never questioned it before, I just assumed the order would hold because this technique has always worked for me in the other browsers. But I suppose I've never seen it stated anywhere that the order is guaranteed. Maybe it's not? Any insight would be awesome. Thanks.

• return a php associative array to javascript array

  - by Eric Sim

  I am trying to return a php associative array to javascript array through ajaxRequest.responseText Here's what I do. First in php, I do this: $encoded = json_encode($thisarray); echo $encoded; If I echo $encoded, I get {"a":"apple,arrow","b":"boy,bank","c":"cat,camp"} Then in js script, thisarray = new Array(); thisarray = ajaxRequest.responseText; If I alert thisarray, I get {"a":"apple,arrow","b":"boy,bank","c":"cat,camp"} That's wrong since alerting an array should give error. But in this case, when I alert thisarray, I get the full array!! Needless to say, I can't call my value out of thisarray, since it is yet defined as an array. Anyone can tell me what am I missing here?

  Hey Guys, i hope someone can help me out on this one here. I use several associative arrays in my php application and i'm using to php documentor to comment my sources. I never really did specified comments for the arrays in an array, but now i need to do that and dont know how. $array = array('id' => 'test', 'class' => 'tester', 'options' => array('option1' => 1, 'option2' => 2)) So how do i comment this array in the correct way for @var and @param comments? I could do this like this, but dunno, if this is correct: @param string $array['id'] @param string $array['class'] @param int $array['options']['option1'] But how to this for the var part? I hope someone can lead me to the right direction. Thanks in advance for any help. Regards

• Dynamically creating/inserting into an associative array in PHP

  - by emil.mp

  I'm trying to build an associative array in PHP dynamically, and not quite getting my strategy right. Basically, I want to insert a value at a certain depth in the array structure, for instance: $array['first']['second']['third'] = $val; Now, the thing is, I'm not sure if that depth is available, and if it isn't, I want to create the keys (and arrays) for each level, and finally insert the value at the correct level. Since I'm doing this quite a lot in my code, I grew tired of doing a whole bunch of "array_key_exists", so I wanted to do a function that builds the array for me, given a list of the level keys. Any help on a good strategy for this is appreciated. I'm sure there is a pretty simple way, I'm just not getting it...

• Unable to send an associative array in JSON format in Zend to client

  - by Anorflame

  Hi, In one of my actions in a controller, I'm using the json view helper to send back a response to an ajax request. On the client side I alert the data that is passed to the success callback function. It works fine as long as the response is a number or an array with default keys. Once I try to send an associative array, it alerts with [object Object]. Server code: $childArray = array('key'=>'value'); $this->_helper->json($childArray); javascript: function displayChildren(data){ alert(data); } ... $.ajax({ url: "/po/add", dataType: "json", data: {format: "json"}, success: displayChildren }); I have no idea what am I doing wrong here, so any help would be appreciated...

• Formatting associative array declaration

  - by Drew Stephens

  When declaring an associative array, how do you handle the indentation of the elements of the array? I've seen a number of different styles (PHP syntax, since that's what I've been in lately). This is a pretty picky and trivial thing, so move along if you're interested in more serious pursuits. 1) Indent elements one more level: $array = array( 'Foo' => 'Bar', 'Baz' => 'Qux' ); 2) Indent elements two levels: $array = array( 'Foo' => 'Bar', 'Baz' => 'Qux' ); 3) Indent elements beyond the array constructor, with closing brace aligned with the start of the constructor: $array = array( 'Foo' => 'Bar', 'Baz' => 'Qux' ); 4) Indent elements beyond the array construct, with closing brace aligned with opening brace: $array = array( 'Foo' => 'Bar', 'Baz' => 'Qux' ); Personally, I like #3—the broad indentation makes it clear that we're at a break point in the code (constructing the array), and having the closing brace floating a bit to the left of all of the array's data makes it clear that this declaration is done.

• Associative array challenges, or examples?

  - by Aerovistae

  I understand well when and how to use an associative array, but I'm trying to teach a friend to program and I'm having some trouble with this particular concept. I need a good set of problems whose solutions are best implemented through the use of maps/hashes/associative arrays/dictionaries. I googled all over and couldn't find any. I was hoping someone might know of some, or perhaps get a community wiki sort of answer. That way I can say, here's our problem, and here's how we could effectively solve it through the use of an associative array... It's one of those cases where when I'm programming and I run into a situation that calls for a dictionary, I recognize it, but I can't seem to make up any such situations to use for a demonstration.

• Compare two associative arrays and create a new array with the matched arrays, PHP

  I have this two arrays: $arr1=array( array("id" => 8, "name" => "test1"), array("id" => 4, "name" => "test2"), array("id" => 3, "name" => "test3") ); $arr2=array( array("id" => 3), array("id" => 4) ); How can i "extract" arrays from $arr1, where id have same value in $arr2, into a new array and leave the extracted array also in a new array, without taking into account key orders? The output i am looking for should be: $arr3=array( array("id" => 8, "name" => "test1") ); $arr4=array( array("id" => 4, "name" => "test2"), array("id" => 3, "name" => "test3") ); Thanks
