You can use pathinfo , which returns information about the path to the file.

Example:

 $path_parts = pathinfo('/www/htdocs/inc/lib.inc.php'); echo $path_parts['dirname'], "\n"; echo $path_parts['basename'], "\n"; echo $path_parts['extension'], "\n"; // расширение файла echo $path_parts['filename'], "\n";

Accordingly, you can write like this:

 $path = 'text.txt'; echo pathinfo($path)['extension'];

Using substr (Returns a substring) and strrpos (Returns the position of the last occurrence of a substring in a string):

 $path = 'text.txt'; echo substr($path, strrpos($path, '.') + 1);
