EXAMPLES
       Example #1

	      Using gd_info(3)

	      <?php
	      var_dump(gd_info());
	      ?>

	      The above example will output something similar to:

	      array(9) {
		["GD Version"]=>
		string(24) "bundled (2.0 compatible)"
		["FreeType Support"]=>
		bool(false)
		["T1Lib Support"]=>
		bool(false)
		["GIF Read Support"]=>
		bool(true)
		["GIF Create Support"]=>
		bool(false)
		["JPEG Support"]=>
		bool(false)
		["PNG Support"]=>
		bool(true)
		["WBMP Support"]=>
		bool(true)
		["XBM Support"]=>
		bool(false)
	      }
