PHP Strings: How to Get the Extension of a File

EXE or GIF or DLL or …

Most of the code chunks I’ve seen about getting a file extension from a string are based on some sort of string manipulation.

If you want to get the filename extension with PHP is better to use pathinfo() than string manipulations

$filename = '/my/path/image.jpeg';
echo substr($filename, strrpos($filename, '.') + 1);

Howerver there is a more elegant solution.

$filename = '/my/path/image.jpeg';
echo strtolower(pathinfo($filename, PATHINFO_EXTENSION));

Thus you rely on PHP built in functions and it’s harder to overlook the exact string manipulation approach.

PPK is right! Stop developing everything as a iPhone app. First that doesn’t work on any device except iPhone and it’s difficult to maintain. In reverse you should begin doing your mobile web site version. Hopefully with HTML5.

Do as Twitter did … or you’d be looking at http://m.digg.com/ – that’s the right way.
