How to check for PHP GD Library

You can also use custom php code to check for PHP GD support. For this we will be using function_exists and extension_loaded functions. Here is the code. Save this file as gdinfo.php and run it on server.

<?php
  if (extension_loaded('gd') && function_exists('gd_info')) {
    echo 'PHP GD library is enabled in your system.';
  }
  else {
    echo 'PHP GD library is not enabled on your system.';
  }
?>
