How to get file extension (without parsing file name)

Get file extension without use of explode function of preg functions

You can use pathinfo function - it will return an array with elements like:

• dirname
• basename
• extension
• filename

Reading those values you will get proper values.

<?php
 $path_parts = pathinfo('/var/www/htdocs/index.php');
 echo $path_parts['dirname'];
 echo $path_parts['basename'];
 echo $path_parts['filename']; // since PHP 5.2.0
 echo $path_parts['extension'];
 ?>
