PHP搜索匹配阵列列 [英] PHP Search Array column for match

问题描述

我有一个数组如下，其中有多个列。我想在一个特定的值的第一列进行搜索，并且具有匹配返回的行。这是可能做到？

I have an array as below, which has multiple columns. I want to search in the first column for a specific value, and have the rows that match returned. Is that possible to do?

例如：

Array (
[0] => Array ( [id] => 1 [column2] => value2 [column3] => value3 [column4] => value4 [column5] => value5 ) 
[1] => Array ( [id] => 1 [column2] => value2 [column3] => value3 [column4] => value4 [column5] => value5 ) 
[2] => Array ( [id] => 2 [column2] => value2 [column3] => value3 [column4] => value4 [column5] => value5 
)

所以我们可以说我想要搜索的ID列1，有结果显示。如何才能做到这一点？太谢谢你了！

So let's say I want to search the "id" column for "1" and have the results displayed. How can this be done? Thank you so much!

推荐答案

既然你有一个嵌套的阵列你需要两个迭代：

Since you have an nested Array you need two iterations:

$filtered = array();
$rows = Your Array;
foreach($rows as $index => $columns) {
    foreach($columns as $key => $value) {
        if ($key == 'id' && $value == '1') {
            $filtered[] = $columns;
        }
    }
}

这应该做的工作。
