Example #1 parsekit_func_arginfo() example
<?php
function foo($bar, stdClass $baz, &$bomb, $bling = false) {
}
var_dump(parsekit_func_arginfo('foo'));
?>
以上例程会输出:
array(4) { [0]=> array(3) { ["name"]=> string(3) "bar" ["allow_null"]=> bool(true) ["pass_by_reference"]=> bool(false) } [1]=> array(4) { ["name"]=> string(3) "baz" ["class_name"]=> string(8) "stdClass" ["allow_null"]=> bool(false) ["pass_by_reference"]=> bool(false) } [2]=> array(3) { ["name"]=> string(4) "bomb" ["allow_null"]=> bool(true) ["pass_by_reference"]=> bool(true) } [3]=> array(3) { ["name"]=> string(5) "bling" ["allow_null"]=> bool(true) ["pass_by_reference"]=> bool(false) } }
