  Extension ext/fileinfo.

This module guesses the content type and encoding of a file by looking for certain magic byte sequences at specific positions within the file.

.. code-block:: php
   
   <?php
   $finfo = finfo_open(FILEINFO_MIME_TYPE); // return mime type ala mimetype extension
   foreach (glob('*') as $filename) {
       echo finfo_file($finfo, $filename) . PHP_EOL;
   }
   finfo_close($finfo);
   ?>
