If you’re developing on Kohana framework and your server is setup with Apache and FastCGI, you’ll run into some weird trouble regarding URL processing. This is happening because Kohana’s Router class is not looking at the REQUEST_URI key in the $_SERVER global, and gets the PHP_SELF...

Listing the files in a directory in PHP is as simple as 1 line: $aList = scandir( '/tmp' ); print_r( $aList ); This will retrieve all the files in the specified directory (including “.” and “..”): Array ( [0] => . [1] => .. ...

constant A constant is an identifier (name) for a simple value. As the name suggests, that value cannot change during the execution of the script (except for magic constants, which aren’t actually constants). A constant is case-sensitive by default. By convention, constant identifiers are always...

When I need to develop a fast-growing, flexible and complex management application that needs to be done in a very short time, I use a CodeIgniter - Rapyd “bundle” that I’ve built to work, which can be turned into a really complex application. Actually, I’ve built a complex management...

I’ve seen here the shortest xml2array implementation: function xml2array($xml) { $xmlary = array(); $reels = '/<(\w+)\s*([^\/>]*)\s*(?:\/>|>(.*)<\/\s*\\1\s*>)/s’; $reattrs = ‘/(\w+)=(?:”|\’)([^"\']*)(:?”|\’)/’; preg_match_all($reels, $xml,...

If you have a 2.7 GB file, file_exists(’./filename’) works but is_file( ‘./filename’ ); fails gracefully. Not even Apache handles these kind of files very well so take care.

Redirecting the output is useful everywhere, including in php. By using `exec()` to import a .sql file into mysql, everything goes smoothly. Until you get some errors. Mysql sends the errors it encounters to stderr instead of stdout. So… you get the command status 1 (something went bad), but no...
