Subject: [PHP-DEV] Type hints revisited [IllegalArgumentException instead of
E_ERROR]
| I've implemented an additional feature for type hints that will throw an
| exception instead of bailing out in case an incorrect type is passed.
|
| Test script:
|
| <?php
| class Date { }
| class Article {
| public function setCreated_at(Date $date) {
| echo __CLASS__, '::', __FUNCTION__, ' called with ';
| var_export($date);
| echo "\n";
| }
|
| public function setLastchange([Date] $date) {
| echo __CLASS__, '::', __FUNCTION__, ' called with ';
| var_export($date);
| echo "\n";
| }
| }
|
| $a= new Article();
| $a->setLastchange(new Date());
| $a->setLastchange(NULL); // Passes
| $a->setCreated_at(new Date());
|
| try {
| $a->setCreated_at(NULL); // Fails
| } catch (IllegalArgumentException $e) {
| echo "Caught: "; var_dump($e);
| }
|
| $a->setCreated_at(1); // Fails
| echo "Alive"; // Will not show up
| ?>
|
| Output:
| ---------------------------------------------------------------------
| thekid@friebes:~/devel/php > ./php5/sapi/cli/php hints.php

| }
