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
)
) |
