PHP find file extension

This 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.

$fileName = '\path\to\file\afile.jpg';
$ext = substr(strrchr($fileName, '.'), 1);
echo $ext;

The output here is ‘jpg’;
