如何按值过滤二维数组
我将如何创建一个按值过滤二维数组的函数？
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
)
我将如何过滤数组以仅显示name键中包含特定值的那些数组？例如name = 'CarEnquiry'。
结果输出为：
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
我忘了提及搜索值应该是可互换的-即name = 'CarEnquiry'或name = 'Finance'。

将PHP的array_filter函数与回调一起使用。$new = array_filter($arr, function ($var) { return ($var['name'] == 'CarEnquiry');});编辑：如果需要可互换，则可以稍微修改代码：$filterBy = 'CarEnquiry'; // or Finance etc.$new = array_filter($arr, function ($var) use ($filterBy) { return ($var['name'] == $filterBy);}); -

<?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');?>
