PHP's forward compatible version compare

admin — Wed, 25 Nov 2009 23:41:11 +0000

Sometimes the code is forward compatible, for example when it's compatible with all future PHP5 releases, put PHP's version_compare function does not support this (Perhaps because they know that they always break compatibility with every minor release!!!). This function supports .x, for the above example it's : 5.x

admin — Wed, 25 Nov 2009 05:50:25 +0000

PHP's file system manipulation functions are not as complete as they should be specially when it comes to manging recursive folders. For addressing part of this issue i decided to write a smart function which can handle recursive file/folder copy easily.

As you may have noticed there are feature that i didn't have time to implement , so if you have time to extend this function please notify me as well :). It's also shared here

Alpha support for PHP's imagecopymerge function

admin — Mon, 23 Nov 2009 05:39:31 +0000

I came up with another idea which is much faster than his solution, (it may need a little bit more memory)
