  • Get Array value by string of keys

    - by Esben Petersen
    Hello, i'm building a template engine for my next project, which is going great. It replaces {tag} with a corresponding value. But, i want {tag[0][key]} to be replaced as well. All i need to know is how to get the value, if i have the string representation of the array and key, like this: $arr = array( 0=>array( 'key'=>'value' ), 1=>array( 'key'=>'value2' ) ); $tag = 'arr[0][key]'; echo($$tag); This is a very simple version of the problem, i hope you understand it. Or else i would be happy to anwser any questions about it :) Thanks for any help in advantage

  • replacing the beginning and end but not the same chars within a string

    - by Jordan Trainor
    lines = "some stuff\"some other \"stuff\"\""; lines = lines.Replace("\"", "\""); lines = lines.Replace("\"", "\""); in its current context and in its simplest form these two actions seem absolutely pointless but when I put this into code it will be not be pointless and will have a purpose other than replacing itself with itself. OK so I have the String lines that has 4 escaped quotation marks and I wish to replace the first quote with a quote and the end quote with a quote how would I accomplish this without replacing any of the inner quotes?

  • remove a varchar2 string from the middle of table data values

    - by Michelle Daniel
    Data in the file_name field of the generation table should be an assigned number, then _01, _02, or _03, etc. and then .ldf (example 82617_01.pdf). Somewhere, the program is putting a state name and sometimes a date/time stamp, between the assigned number and the 01, 02, etc. (82617_ALABAMA_01.pdf or 19998_MAINE_07-31-2010_11-05-59_AM.pdf or 5485325_OREGON_01.pdf for example). We would like to develop an SQL statement to find the bad file names and fix them. In theory it seems rather simple to find file_names that include a varchar2 data type and remove it, but putting the statement together is beyond me. Any help or suggestions apprecuiated. Something like ........... UPDATE GENERATION SET FILE_NAME (?) WHERE FILE_NAME (?...LIKE '%STRING%');?

  • MySQL - Where - search string - MATCH.

    - by Jamie
    Hi guys, Quick question. I'm in a bit of a rush but if someone could quickly point me in the right direction I would be very very happy. I have a field in the db, let's call it field_a which returns a string in the format "20,50,60,80" etc. I wish to do a query which will search in this field to see if 20 exists. Could I use MySQL MATCH or is there a better way? Thank you!

  • Problem storing string containing quotes

    - by Jack
    I have the following table - $sql = "CREATE TABLE received_queries ( sender_screen_name varchar(50), text varchar(150) )"; I use the following SQL statement to store values in the table $sql = "INSERT INTO received_queries VALUES ('$sender_screen_name', '$text')"; Now I am trying to store the following string as 'text'. One more #haiku: Cotton wool in mind; feeling like a sleep won't cure; I need some coffee. and I get the following error message Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 't cure; I need some coffee.')' at line 1 I think must be a pretty common problem. How do I solve it?

  • Checking if a string's characters are ascending alphabetically and its ascent is evenly spaced python

    - by FRU5TR8EDD
    So need to check if a string's characters are ascending alphabetically and if that ascent is evenly spaced. a = "abc" b = "ceg" So a is alphabetically ascending and it's spacing is 1 (if you convert to the ordinal values they are 97,98,99). And b is also alphabetically ascending and it's spacing is 2 (99,101,103). And I am sticking with the following code: a = 'jubjub' words1 = [] ords = [ord(letter) for letter in a] diff = ords[1] - ords[0] for ord_val in range(1, len(ords)-1): if diff > 0: if ords[ord_val + 1] - ords[ord_val] == diff: if a not in words1: words1.append((a, diff)) print words1 How come 'jubjub' works, 'ace' works, but 'catcat' doesn't?

  • C appending char to char*

    - by Ostap Hnatyuk
    So I'm trying to append a char to a char*. For example I have char *word = " "; I also have char ch = 'x'; I do append(word, ch); Using this method.. void append(char* s, char c) { int len = strlen(s); s[len] = c; s[len+1] = '\0'; } It gives me a segmentation fault, and I understand why I suppose. Because s[len] is out of bounds. How do I make it so it works? I need to clear the char* a lot as well, if I were to use something like char word[500]; How would I clear that once it has some characters appended to it? Would the strlen of it always be 500? Thanks in advance.

  • Instantiating class by string using PHP 5.3 namespaces

    - by Kevin
    I can't get around an issue instantiating a new class by using a string variable and PHP 5.3. namespaces. For example, this works; $class = 'Reflection'; $object = new $class(); However, this does not; $class = '\Application\Log\MyClass'; $object = new $class(); A fatal error gets thrown stating the class cannot be found. However it obviously can be instantiated if using the FQN i.e.; $object = new \Application\Log\MyClass; I've found this to be aparrent on PHP 5.3.2-1 but not not in later versions. Is there a work around for this?

  • Getting the last element of a Postgres array, declaratively

    - by Wojciech Kaczmarek
    How to obtain the last element of the array in Postgres? I need to do it declaratively as I want to use it as a ORDER BY criteria. I wouldn't want to create a special PGSQL function for it, the less changes to the database the better in this case. In fact, what I want to do is to sort by the last word of a specific column containing multiple words. Changing the model is not an option here. In other words, I want to push Ruby's sort_by {|x| x.split[-1]} into the database level. I can split a value into array of words with Postgres string_to_array or regexp_split_to_array functions, then how to get its last element?

  • ASP.NET MVC4: How to convert an IEnumerable to a string for ViewBag

    This is what I'm trying to do, but it doesn't work: HardwareType hwt = new HardwareType { HType = "PC" }; IEnumerable<Hardware> Pcs = db.Hardware.Where(h => h.HardwareType.Contains(hwt)); ViewBag.Pcs = Pcs.ToString(); So how do I convert my IEnumerable to a string (or other primitive data type) so the compiler won't give me an error when I try to use it in my Razor? @foreach (var item in ViewBag.Pcs) { <li><a href="#" class="btn"><i class="icon-hdd"></i> @item.HType</a></li> }

  • How do I create English-language list (name1, name2, AND name3) in Ruby on Rails?

    - by Angela
    Quite possibly there could be a rails magic I've missed, but I'm guessing it will be in Ruby. I have a model called Company which has_many Contacts. Suppose Company has Contact 1, Contact 2, Contact 3, and Contact 4. When I create a textblog for each Contact, I want to output the following (where Contact = Contact 1) "Hi, Contact 1, I am also writing to Contact 2, Contact 3, and Contact 4." So it needs to extract the Contact in the salutation and then list them, inserting "and" before the last Contact in the list.

  • Detect non-closed connections to SQL

    - by JoeJoe
    I've inherited a very large project in ASP.net, SQL 2005 and have found where some SQL connections are not closed - which is bad. Without going thru every line of code, is there a way to detect if connections are not being closed? Performance counter? as a follow up - how does SQL reclaim unclosed connections. I'm using non-pooled connectionstring.

  • Strings, regexp and files

    - by A Moose
    <?php $iprange = array( "^12\.34\.", "^12\.35\.", ); foreach($iprange as $var) { if (preg_match($var, $_SERVER['REMOTE_ADDR'])) { I'm looking to have a list that will constitute each of the values inside the array. Let's call it iprange.txt, from which I would extract the variable $iprange. I would also be updating the file with new ranges, but I also want to convert those strings to regexp if that's something that's needed in php, as it is in the above example. If you could help me with the two following issues: I understand that somehow I would be using an array include, but I'm not sure how to implement it. I would like to run a cron that would update the text file and turn it into a regexp acceptable for use in the above example, if you think regexp is a good idea and there isn't another option. I know how to apply a cron in a directadmin gui, but I don't know what the cronned file would look like.

  • Perl - string matching issue

    - by user2886545
    I have a problem I cannot understand. I have this string: gene_id "siRNA_Z27kG1_20543"transcript_id "siRNA_Z27kG1_20543_X_1";tss_id "TSS124620" And I want to change the gene_id. So, I have the following code: if ($line =~ /;transcript_id "([A-Za-z0-9:\-._]*)(_[oxOX][_.][0-9]*)";/) { $num = $2; $line =~ s/gene_id "([A-Za-z0-9:\-._]*)";/gene_id "$1$num";/g; print $new $line."\n"; } The aim of my code is to change siRNA_Z27kG1_20543 for siRNA_Z27kG1_20543_X_1. However, my code does not produce that output. Why? I can't understand that. My regex needs to be as it is because I match other strings (this time with success). Thanks.

  • Help Fix a bug - Unexpected T_STRING

    - by thecoshman
    So I have just rebuilt my server, just on local network. Stick my site back on it, try to run the code, and I get a anice T_STRING error. This is all very strange, as I have not changed the code :S <?php $window_ID = -1; if(isset($_POST["window_ID"]) AND $_POST["window_ID"] != null){ $window_ID = trim($_POST["window_ID"]); } ?> This is the start of the file, apter this rather loverly snipit of PHP the rest is just XMl, yet on line 6 appertnlty there is an unexpected T_STRING, which is strange considering all that is on that line is the ?>, then the XML starts up... Any one got any ideas what has gone wrong here? Any chance it ould be magic quotes? I had turned it of before, but I want to now update my code to check for the magic quotes and avoid its stupid actions.

  • Java - Optimize finding a string in a list

    - by Mark
    I have an ArrayList of objects where each object contains a string 'word' and a date. I need to check to see if the date has passed for a list of 500 words. The ArrayList could contain up to a million words and dates. The dates I store as integers, so the problem I have is attempting to find the word I am looking for in the ArrayList. Is there a way to make this faster? In python I have a dict and mWords['foo'] is a simple lookup without looping through the whole 1 million items in the mWords array. Is there something like this in java? for (int i = 0; i < mWords.size(); i++) { if ( word == mWords.get(i).word ) { mLastFindIndex = i; return mWords.get(i); } }

How do I convert the string to a node so that the method will accept the string.
