PHP 5.3.0 USE关键字 - 如何在5.2中反向移植？

Question

我有一些代码已经使用PHP中的USE函数为php 5.3.0编写

有人可以帮我改变这个为5.2.9工作吗？

$available  = array_filter($objects, function ($object) use ($week) { 
    return !in_array($object, $week);
});

谢谢您的帮助

不太好,但这将是一个等效的实现.

class MyWeekFilter {
    protected $_week;

    public function __construct($week) {
        $this->_week = $week;
    }

    public function filter($object) {
        return !in_array($object, $this->_week);
    }
}

$filter    = new MyWeekFilter($week);
$available = array_filter($objects, array($filter, 'filter'));
