Find File Extension In PHP
Published by philipnorton42 on Mon, 02/23/2009 - 12:33This simple code example uses a combination of strrchr to find the last occurrence of a string and substr to return part of the string in order to find the file extension for a given filename. This is ideal if you want to quickly find a file extension.
$ext = substr(strrchr($fileName, '.'), 1);
This code can be used in the following way.
1 2 3 | $fileName = '\path\to\file\afile.wibble'; $ext = substr(strrchr($fileName, '.'), 1); echo $ext; |
The output here is 'wibble';
