如何创建按值筛选二维数组的函数？

给定以下数组：

Array
(
    [0] => Array
        (
            [interval] => 2014-10-26
            [leads] => 0
            [name] => CarEnquiry
            [status] => NEW
            [appointment] => 0
        )

    [1] => Array
        (
            [interval] => 2014-10-26
            [leads] => 0
            [name] => CarEnquiry
            [status] => CALL1
            [appointment] => 0
        )

    [2] => Array
        (
            [interval] => 2014-10-26
            [leads] => 0
            [name] => Finance
            [status] => CALL2
            [appointment] => 0
        )

    [3] => Array
        (
            [interval] => 2014-10-26
            [leads] => 0
            [name] => Partex
            [status] => CALL3
            [appointment] => 0
        )

如何筛选数组以仅显示那些在键中包含特定值的数组？例如。namename = 'CarEnquiry'

生成的输出将为：

Array
(
    [0] => Array
        (
            [interval] => 2014-10-26
            [leads] => 0
            [name] => CarEnquiry
            [status] => NEW
            [appointment] => 0
        )

    [1] => Array
        (
            [interval] => 2014-10-26
            [leads] => 0
            [name] => CarEnquiry
            [status] => CALL1
            [appointment] => 0
        )

    )

编辑

我忘了提到搜索值应该是可互换的 - 即或。name = 'CarEnquiry'name = 'Finance'

答案 1

使用 PHP 的 array_filter 函数和回调。

$new = array_filter($arr, function ($var) {
    return ($var['name'] == 'CarEnquiry');
});

编辑：如果需要互换，可以稍微修改代码：

$filterBy = 'CarEnquiry'; // or Finance etc.

$new = array_filter($arr, function ($var) use ($filterBy) {
    return ($var['name'] == $filterBy);
});

答案 2

<?php



    function filter_array($array,$term){
        $matches = array();
        foreach($array as $a){
            if($a['name'] == $term)
                $matches[]=$a;
        }
        return $matches;
    }

    $new_array = filter_array($your_array,'CarEnquiry');

?>
