get_defined_functions

Returns an array of all defined functions (PHP 4 >= 4.0.4, PHP 5)
array get_defined_functions ( )

Gets an array of all defined functions.

Return Values

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

Examples

Example 762. get_defined_functions() example

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

$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
       )

)
