SYNOPSIS
array get_defined_functions (void ) DESCRIPTION
Gets an array of all defined functions. RETURN VALUES

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 ) ) SEE ALSO
