PHP Manual for

get_defined_functions

(PHP 4 >= 4.0.4)

get_defined_functions -- Returns an array of all defined functions

Description

array get_defined_functions ( void )

This function 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).


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

$arr = get_defined_functions();

print_r($arr);
?>

Will output something along the lines of:

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    )

)
