  • PHP Loop Over ONLY Different Arrays

    - by Steven
    Hello, I have a single array with several of the same values. And I only want to loop over DIFFERENT values. How could I go about doing this? Example 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97_108 166-01 001;09;UO;_86_97_108 166-01 001;09;UO;_86_97_108_119 166-01 001;09;UO;_86_97_108_119 I have that in a single array, but I only want to loop for the different ones. So it would loop once for nothing, then once for _86, then once for _86_97, then once for _86_97_108, and then once for _86-97_108_119. So only loop for different key values, or would there be a way to count the number of different keys?

  • how to write this conditions in php

    - by Mac Taylor
    hey guys , im writing a class and im wondering how i can write a condition statement in this way : $this->referer= (!empty($_SERVER['HTTP_REFERER'])) ? htmlspecialchars((string) $_SERVER['HTTP_REFERER']) : ''; i need to find my user_id and this is the usual condtion : if(is_user($user)){ $cookie=cookiedecode($user); $user_id=intval($cookie[0]); } and i think it should be something like this : $this->user_id = (is_user($user)) ?

  • How does PHP PDO work internally ?

    - by Rachel
    I want to use pdo in my application, but before that I want to understand how internally PDOStatement->fetch and PDOStatement->fetchAll. For my application, I want to do something like "SELECT * FROM myTable" and insert into csv file and it has around 90000 rows of data. My question is, if I use PDOStatement->fetch as I am using it here: // First, prepare the statement, using placeholders $query = "SELECT * FROM tableName"; $stmt = $this->connection->prepare($query); // Execute the statement $stmt->execute(); var_dump($stmt->fetch(PDO::FETCH_ASSOC)); while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) { echo "Hi"; // Export every row to a file fputcsv($data, $row); } Will after every fetch from database, result for that fetch would be store in memory ? Meaning when I do second fetch, memory would have data of first fetch as well as data for second fetch. And so if I have 90000 rows of data and if am doing fetch every time than memory is being updated to take new fetch result without removing results from previous fetch and so for the last fetch memory would already have 89999 rows of data. Is this how PDOStatement::fetch works ? Performance wise how does this stack up against PDOStatement::fetchAll ?

  • HTTP authentication logout via PHP

    What is the correct way to log out of HTTP authentication protected folder? There are workarounds that can achieve this, but they are potentially dangerous because they can be buggy or don't work in certain situations / browsers. That is why I am looking for correct and clean solution.

  • Open book PHP test

    - by user275074
    Hi, I have a open-book test this week and I've been notified that the test will be an exercise whereby a chunk of legacy code is provided and a requirement to port the code. I understand what a open-book test is and the requirement of it (to test your thought process etc) but (it's a long shot) what could porting involve? I have a vague idea of what porting is.

  • Need some help to determine the amount of recursive calls in PHP

    - by Ben Fransen
    Hi all, I've got a, I think fairly easy question, but this is bugging me for a while now. So I figured, maybe I can get some help here. Since recursive functions are always a bit tricky, and sometimes a bit unclear to me, I keep struggling to create a nice working solution to get my menudata. In one of my classes I have this function, which gives me all menu-items recursivly. The thing I want is to determine at which recursionlevel a certain object was retrieved so I can create a nicely looking HTML output with indents for the levels of nesting. public function GetObjectList($parentID = 0, $objectlist = null) { if(is_null($objectlist)) { $objectlist = new ObjectList("Model_Navigation"); } $query = MySQL::Query("SELECT * FROM `Navigation` WHERE `WebsiteID` = ".SITE_ID. " AND `LanguageID` = ".LANG_ID." AND `ParentID` = ".$parentID); while($result = MySQL::FetchAssoc($query)) { $object = new Model_Navigation(); $object->ID = $result["ID"]; $object->WebsiteID = $result["WebsiteID"]; $object->LanguageID = $result["LanguageID"]; $object->ParentID = $result["ParentID"]; $object->Name = $result["Name"]; $object->Page = Model_Page::GetObjectByID($result["PageID"]); $object->ExternalURL = $result["ExternalURL"]; $object->Index = $result["Index"]; $object->Level = [here lies my problem]; $objectlist->Add($object); self::GetObjectList($object->ID, $objectlist); } return $objectlist; } Hope to hear from you! Greetings from Holland, Ben Fransen

    - by Jordan Pagaduan
    $dbc = mysql_connect('localhost','root','') or die (mysql_error()); mysql_select_db('payroll') or die (mysql_error()); $sql = "SELECT * FROM employee ORDER BY employee_id DESC"; $result = mysql_query($sql); while($row = mysql_fetch_array($result)) { echo " <tr> <td style=\"padding-left: 20px; border-bottom: 1px solid #999; border-right: 1px solid #999;\">".$row['first_name']."

  • PHP mySQL database check

    - by kielie
    Hi guys, I am having endless troubles with duplicate entries, so I need to check the database, and if a user has already entered that day, their entry will not be submitted and they will be redirected to a landing page that tells them they have already entered that day, and that they may only enter again tomorrow. The field I would like to check is the id_number field in the database, since each user has a unique id number, so basically, if a user with the same id number submitted on the same date they should be redirected to a landing page, how would I go about doing this? I am still new to a lot of this, so please be forgiving. Thanx in advance.

  • Design Practice Retrieve Multiple Users - PHP

    - by pws5068
    Greetings all, I'm looking for a more efficient way to grab multiple users without too much code redundancy. I have a Users class, (here's a highly condensed representation) Class Users { function __construct() { ... ... } private static function getNew($id) { // This is all only example code $sql = "SELECT * FROM Users WHERE User_ID=?"; $user = new User(); $user->setID($id); .... return $user; } public static function getNewestUsers($count) { $sql = "SELECT * FROM Users ORDER BY Join_Date LIMIT ?"; $users = array(); // Prepared Statement Data Here while($stmt->fetch()) { $users[] = Users::getNew($id); ... } return $users; } // These have more sanity/security checks, demonstration only. function setID($id) { $this->id = $id; } function setName($name) { $this->name = $name; } ... } So clearly calling getNew() in a loop is inefficient, because it makes $count number of calls to the database each time. I would much rather select all users in a single SQL statement. The problem is that I have probably a dozen or so methods for getting arrays of users, so all of these would now need to know the names of the database columns which is repeating a lot of structure that could always change later. What are some other ways that I could approach this problem? My goals include efficiency, flexibility, scalability, and good design practice.

  • Consuming RSS Feed In PHP

    - by mrduclaw
    I'm trying to use an RSS feed from my blog on the news section on another site. Everything seems to be working fine until I use something like an ellipsis on my blog. The expected output is: One more time…less fail Although this is no joking matter… The actual output is: One more time?less fail Although this is no joking matter… The problem is that ? should be a .... The code I'm using is the same for the first line (the blog title) and the second line (the blog contents) and that code is: $a = utf8_decode($a); print("$a"); Where $a is the string from the RSS feed. Can anyone point in the right direction why that code would work correctly for the body (second line) and not for the title (first line)? Or suggest a better way to do this? Thanks!

  • [PHP] access array element by value

    - by Brandon
    array( [0] name => 'joe' size => 'large' [1] name => 'bill' size => 'small' ) I think i'm being thick, but to get the attributes of an array element if I know the value of one of the keys, I'm first looping through the elements to find the right one. foreach($array as $item){ if ($item['name'] == 'joe'){ #operations on $item } } I'm aware that this is probably very poor, but I am fairly new and am looking for a way to access this element directly by value. Or do I need the key? Thanks, Brandon

  • PHP: Replace umlauts with closest 7-bit ASCII equivalent in an UTF-8 string

    - by BlaM
    What I want to do is to remove all accents and umlauts from a string, turning "lärm" into "larm" or "andré" into "andre". What I tried to do was to utf8_decode the string and then use strtr on it, but since my source file is saved as UTF-8 file, I can't enter the ISO-8859-15 characters for all umlauts - the editor inserts the UTF-8 characters. Obviously a solution for this would be to have an include that's an ISO-8859-15 file, but there must be a better way than to have another required include? echo strtr(utf8_decode($input), 'ŠŒŽšœžŸ¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ', 'SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy'); UPDATE: Maybe I was a bit inaccurate with what I try to do: I do not actually want to remove the umlauts, but to replace them with their closest "one character ASCII" aequivalent.

  • PHP count total files in directory AND subdirectory function

    - by Neoweiter
    I need to get a total count of JPG files within a specified directory, including ALL it's subdirectories. No sub-sub directories. Structure looks like this : dir1/ 2 files subdir 1/ 8 files total dir1 = 10 files dir2/ 5 files subdir 1/ 2 files subdir 2/ 8 files total dir2 = 15 files I have this function, which doesn't work fine as it only counts files in the last subdirectory, and total is 2x more than the actual amount of files. (will output 80 if I have 40 files in the last subdir) public function count_files($path) { global $file_count; $file_count = 0; $dir = opendir($path); if (!$dir) return -1; while ($file = readdir($dir)) : if ($file == '.' || $file == '..') continue; if (is_dir($path . $file)) : $file_count += $this->count_files($path . "/" . $file); else : $file_count++; endif; endwhile; closedir($dir); return $file_count; }

  • Returning unique values of a multi-dimensional array with CodeIgniter PHP

    - by Michael Bradley
    Hi - I'm developing a property rentals website. The search results page will contain a list of property results. It is my intention to redefine the results, say by town, country, property type etc. So let's say for example the user searches 'France'. All of the relative properties will be returned and displayed in a list. However, I also need to reuse this array, to display only unique town names from the search results array. e.g. Montpellier, Lyon, Rennes, Nice etc. The idea is when use user click on 'Nice', only the 'Nice' properties would return. I would also like to display how many properties are in that town. The closest example as to what I want to achieve. http://www.miaandmaggie.com/dog-collars-leashes.html Any ideas how I can use my search array to display the unique towns of the search? Many thanks!

  • Should you use a PHP Framework?

    - by christopher-mccann
    I have asked before about selecting a framework but I have never actually asked should you a framework? In the past I have never used one but I am being drawn more and more to the idea to speed up development time. I am really concerned about the performance of the application though. Does anyone have any views on whether it is a good idea or not to use a framework? The performance of the apps built on top of it will be crucial. Thanks

  • PHP: Recursively get children of parent

    - by Nic Hubbard
    I have a function which gets the ids of all children of a parent from my DB. So, if I looked up id 7, it might return an array with 5, 6 and 10. What I then want to do, is recursively find the children of those returned ids, and so on, to the final depth of the children. I have tried to write a function to do this, but I am getting confused about recursion. function getChildren($parent_id) { $tree = Array(); $tree_string; if (!empty($parent_id)) { // getOneLevel() returns a one-dimentional array of child ids $tree = $this->getOneLevel($parent_id); foreach ($tree as $key => $val) { $ids = $this->getChildren($val); array_push($tree, $ids); //$tree[] = $this->getChildren($val); $tree_string .= implode(',', $tree); } return $tree_string; } else { return $tree; } }//end getChildren() After the function is run, I would like it to return a one-dimentional array of all the child ids that were found.
