Example #1 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 ) )
