在多维数组中查找值和键 [英] Find value and key in multidimensional array

问题描述

我有以下数组:

Array ( 
    [0] => Array ( 
        [word] => 1 
        [question] => php 
        [position] => 11 
    )
    [1] => Array ( 
        [word] => sql 
        [question] => 1 
        [position] => 22 
    ) 
)

我需要查找数组中是否存在 [position] => 22 并保留数组路径以供进一步参考.谢谢.

I need to find if [position] => 22 exists in my array and retain the array path for further reference. Thank you.

推荐答案

你可以试试这个代码:

$array = array 
( 
    array ( 
        "word" => 1,
        "question" => php,
        "position" => 11 
    ),
    array ( 
        "word" => sql,
        "question" => 1,
        "position" => 22 
    ) 
);

foreach($array as $item)
{
    foreach($item as $key=>$value)
    {
        if($key=="position" && $value=="22")
        {
           echo "found";
        }
    }
}
