PHP按特定值的多维数组

Question

我有一个多维的数组，我想让数组只与我的特定值匹配，现在我有一个名为related_users的列，我需要一个语句，只有当这个数组的related_user值为1时，才能获得这个数组的值。

Array
(
[0] => Array
    (
        [id] => 1
        [advertiser] => Hairvolution
        [postdate] => 
        [campaign_period] => 
        [related_users] => 1
        [reporting_period] => 
        [Delivered Impressions] => 1439763
        [Clicks] => 4124
        [Click-Through Rate] => 0.29
    )

[1] => Array
    (
        [id] => 4
        [advertiser] => 
        [postdate] => 
        [campaign_period] => 
        [related_users] => 2
        [reporting_period] => 
        [Delivered Impressions] => 
        [Clicks] => 
        [Click-Through Rate] => 
    )

[2] => Array
    (
        [id] => 7
        [advertiser] => maxlibin
        [postdate] => 
        [campaign_period] => 
        [related_users] => 2
        [reporting_period] => 
        [Delivered Impressions] => 
        [Clicks] => 
        [Click-Through Rate] => 
    )
 [3] => Array
    (
        [id] => 8
        [advertiser] => maxlibin
        [postdate] => 
        [campaign_period] => 
        [related_users] => 1
        [reporting_period] => 
        [Delivered Impressions] => 
        [Clicks] => 
        [Click-Through Rate] => 
    )

[4] => Array
    (
        [id] => 9
        [advertiser] => maxlibin
        [postdate] => 
        [campaign_period] => 
        [related_users] => 1
        [reporting_period] => 
        [Delivered Impressions] => 
        [Clicks] => 
        [Click-Through Rate] => 
    )
}

Answer 1

使用for循环，迭代它并检查related_users值，如果它与1匹配，则将数组附加到新数组。

$arr = array();
for($i=0;$i< count($your_array);$i++) {
    if($your_array[$i]['related_users'] == 1) {
        $arr[] = $your_array[$i];
    }
}
print_r($arr);

Answer 2

我不确定你想要什么，但你可以试试这段代码：

$final = array();
    foreach($arrayName as $arrayItem){
        if ($arrayItem['related_user'] == 1){
            $final[] = $arrayItem;
        }
    }
var_dump($final);

Answer 3

对数组使用foreach，这是迭代数组并检查related_users值的最简单方法，如果值为1，则将其附加到新的数组$result。

$result = array();
foreach($your_array as $Item){
  if ($Item['related_user'] == 1){
     $result[] = $Item;
  }
}
print_r($result);
