Type hinting/castingパッチはPHP5.3.0でも動く

PHP

前のエントリで


PHP5.3.0に上のパッチを当てることもできるようですが、タイプキャストの方しか動作しませんでした。。。残念。。。

とか書いたんですが、モーレツに恥ずかしいことにre2cが入ってませんでした。。。＞＜

とりあえず、

$ sudo yum install -y re2c

でインストールし、Zend/zend_language_scanner.cを削除して再度configure/make/make install。テストを実行すると、全てパスしました。

ついでに、以下のようなコードでも動作確認。

$ cat test.php
<?php
class test
{
    public function hoge(int $a) {
        var_dump($a);
    }
}
$obj = new test();
$obj->hoge(1);
$obj->hoge(PHP_INT_MAX);

/**
 * Catchable fatal error: Argument 1 passed to test::hoge() must be of the type integer, double given
 */
//$obj->hoge(PHP_INT_MAX + 1);

/**
 * Catchable fatal error: Argument 1 passed to test::hoge() must be of the type integer, string given
 */
//$obj->hoge('1');
$ /usr/local/lib/php53/bin/php -n test.php
int(1)
int(2147483647)
$

あー。早くこれ欲しいなぁ。。。
