Why does my AJAX validation code not work properly?

I made a website that depends on PHP, AJAX and Javascript. The problem here is that the website is unstable which means sometimes the validation is working and some times it is not working at all. The validation code is written in JavaScript. Does this mean that we need more special conditions? The code for validation: <script langua...

PHP mycrypt problem, weird characters/warnings.

I have no idea what I'm doing wrong. I just need to be able to encrypt and decrypt without getting weird characters or warnings.

MySQL: Determine Table's Primary Key Dynamically

Code Separation Paradox: Create HTML Tree from Multi-Dimensional Array AND Keep the HTML Outside of the Recursive Function

This working code seems to be the typical solution to this problem. It takes a multi-dimensional array that holds categories and their subcategories (with no implied limitation on how many levels deep it goes) and creates an HTML unordered list from it, echoing it out onto the page from inside a recursive function. Sub-levels are trave...

SQL query works on testing server but not live... what could be the difference?

PHP REST Clients

I'm trying to connect to a RESTful web service, but I'm having some troubles, especially when sending data over PUT and DELETE. With cURL, PUT requires a file to send, and DELETE is just weird. I'm perfectly capable of writing a client using PHP's socket support and writing the HTTP headers myself, but I wanted to know whether you guys h...

Showing NetBeans where a PHP class is defined

I'm using NetBeans for my PHP programming. Most often it's pretty clever in finding class declarations, especially if they are found in the same project. But sometimes it just refuses to find a class' definition, like a PEAR library's class. Is there a way for me to show NetBeans where a certain class is defined, manually, and enjoy the ...

How can I run several PHP scripts from within a PHP script (like a batch file)?

How can I run several PHP scripts from within another PHP script, like a batch file? I don't think include will work, if I understand what include is doing; because each of the files I'm running will redeclare some of the same functions, etc. What I want is to execute each new PHP script like it's in a clean, fresh stack, with no knowl...

will changing all code to object oriented make memory usage bigger or smaller?

There is a project written in PHP that is just simply all procedural ... step by step calling DB functions, processing, and printing out the output. And then it is changed to totally object oriented -- there is a singleton for the App object, and various functions are invoked through the App object. Someone claims that the memory usage...

Deep copy of PHP array of references

So $array is an array of which all elements are references. I want to append this array to another array called $results (in a loop), but since they are references, PHP copies the references and $results is full of identical elements. So far, the best working solution is: $results[] = unserialize(serialize($array)); which I fear t...

can't access global variables inside a usort function?

I'm trying to do a usort in PHP, but I can't access global variables inside a usort function. I've simplified my code down to bare bones to show what I mean: $testglobal = 1; function cmp($a, $b) { global $testglobal; echo 'hi' . $testglobal; } usort($topics, "cmp"); Assuming the usort runs twice, my expectations is this will...
