Question

如何设置multifilter或multicallback？

我想要City和Confirm一起过滤数据。

输入数据：

$data1 = array(
            "L1" => array('Vanessa', 'Prague', 'OK'),
            "L2" => array('Alex', 'Paris', 'OK'),
            "L3" => array('Paul', 'Paris', 'OK'),
            "L4" => array('John', 'Madrid', 'OK'),
            "L5" => array('Jane', 'London', 'Waiting'),
            "L6" => array('David', 'Prague', 'OK'),
            "L7" => array('Martin', 'Prague', 'Waiting'),
            "L8" => array('Frank', 'Prague', 'OK'),
            "L9" => array('Joseph', 'Prague', 'Waiting'),
            );

过滤代码：

$ByConfirm = 'OK'; 
$ByCity = 'Prague';

以下是我的问题。我尝试使用&&，但它分开工作，我需要$filterByConfirm + $filterByCity的合作

$new = array_filter($data1, $filterByConfirm && $filterByCity);

      $filterByConfirm =  $new = array_filter($data1, function ($var) use ($ByConfirm) {
            return ($var[2] == $ByConfirm); 
      });

      $filterByCity =  $new = array_filter($data1, function ($var) use ($ByCity) {
            return ($var[1] == $ByCity); 
      });

实际结果：

Name    City    Confirm
Vanessa Prague  OK
David   Prague  OK
Martin  Prague  Waiting
Frank   Prague  OK
Joseph  Prague  Waiting

我需要：

Name    City    Confirm
Vanessa Prague  OK
David   Prague  OK
Frank   Prague  OK

最后，这是解决方案： PHP 5.2: Filter array with multiple arguments performance

$arrayToCompare = array('type'=>'fruits','has_name'=>'OK', 'has_color'=>'Prague');

$new = array_filter(
                $data1,
                function ($arr) use ($arrayToCompare) { // PHP 5.3 is required here!!
                    return ($arr[2] == $arrayToCompare['has_name']
                        AND $arr[1] == $arrayToCompare['has_color']);
                }
            );

PHP array_filter多回调
