get_defined_functions - Returns an array of all defined functions

SYNOPSIS
       array get_defined_functions (void  )

DESCRIPTION
	Gets an array of all defined functions.

RETURN VALUES
	Returns a multidimensional array containing a list of all defined functions, both built-in (internal) and user-defined. The internal func-
       tions will be accessible via $arr["internal"], and the user defined ones using $arr["user"] (see example below).

EXAMPLES
       Example #1

	      get_defined_functions(3) example

	      <?php
	      function myrow($id, $data)
	      {
		  return "<tr><th>$id</th><td>$data</td></tr>
";
	      }

	      $arr = get_defined_functions();

	      print_r($arr);
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [internal] => Array
		      (
			  [0] => zend_version
			  [1] => func_num_args
			  [2] => func_get_arg
			  [3] => func_get_args
			  [4] => strlen
			  [5] => strcmp
			  [6] => strncmp
			  ...
			  [750] => bcscale
			  [751] => bccomp
		      )

		  [user] => Array
		      (
			  [0] => myrow
		      )

	      )
