PHP: Get File Extension
June 9th, 2008 posted by err0r

There are many ways to get the file extension of a file. Here is an example of a php function I found to do just that.

<?php
function file_extension($fname)
{
$path_info = pathinfo($fname);
return $path_info[‘extension’];
}
?>

Another way would be to check the actual string and use what’s after the last slash. I picked this up on a forum I visit.

<?php
$filetype = substr($file, strrpos($file, ‘.’) + 1);
?>
