PHP (or "PHP: Hypertext Preprocessor") is a widely-used Open Source scripting language that is created specifically for Web development and can be embedded into HTML.


Using PHP Short Tags
PHP Short Tags refers to '<?' when a full tag is '<?php'. Most PHP installations has short tags support - but there are a few installations that have turned it off. So it is recommended that you don't use the short tags in your app if you plan to distribute it.
Capture the Output of an Included File
It is possible to capture the output of an include to a variable. This is useful for caching and code generation. I found this feature when I was creating a code generation script for IFrame.
Path of the Current File in PHP
There are various methods of find the path of the current file in PHP. But the problem is to find one that is consistent across all servers. The following is a list of the most commonly used methods to find the location of the current file. The definitions are taken from the PHP manual(Predefined Variables) and are modified slightly.

This function expects two arguments - the first argument is the URL and the second one is an array with all the parameters that should be passed with the URL. The function will combine the existing URL with the parameter array and return the resulting URL.
load() Function for PHP - Fetch URL Content

I recently had to develop a small script that will fetch an XML file from the web. All I had to do is download a given URL and read its contents. To my great surprise I found that download the file using my jx Ajax library was much easier than doing it with PHP.

PHP make this very easy by including functions like file_get_contents() that has URL support. Unfortunately, this is a huge security threat - and many servers have disabled this feature in PHP. PHP provide other two method to fetch an URL - Curl and Fsockopen. But to use this I have to write a lot more code. So I decided to create my own function that makes it much more easier.

iFrame PHP Framework
iFrame is my PHP framework - developed for personal use and distributed under the BSD License. I will not recommend using this framework for your projects.
Upload Function
Uploading a file using PHP is not a single step function. To make this easier, I have created a function that will upload a file with just one function call. Just upload('image'); and the file is uploaded! upload() is a function that makes uploading files very easy.
Element Deletion from Array
PHP have a large number of native functions for array operations. When I am coding in javascript, I envy this feature of PHP. Many people have gone to the extend of porting the most needed functions over to javascript. However, you will find that one function is missing in PHP - the remove function for an array element.
