在php中为多维数组提取相等值

我有这个问题。我有一个多维json数组（不问-遗留代码）。我将其转换为PHP数组。我需要提取所有具有相同值的键（在我的示例“666”中）。我需要将每个键分配给一个单独的变量。在我的代码中，我成功地获取了密钥，但我只能将它们分配给另一个数组，或者一次分配给一个变量。请帮忙！！！ 爱V

代码如下：

<?php
//user input
$in = "666";

$outputZ = '[
{"record_id_001":"1"},
{"record_id_002":"13"},
{"record_id_003":"666"},
{"record_id_004":"72661781"},
{"record_id_005":"8762"},
{"record_id_006":"666"},
{"record_id_007":"8762"},
{"record_id_008":"666"},
{"record_id_009":"8762"},
{"record_id_010":"8762"},
{"record_id_011":"666"}
]';

//convert json to php array
//someArray = json_decode($someJSON, true);
$decoZ = json_decode($outputZ, true);

// TESTING (move to comment latter)
//print_r ($decoZ);

//loop through each array an check for user input
//way 1: assign to new array
foreach($decoZ as $array => $number)
foreach($number as $key => $value)
    if (in_array("$in", $number)) {
        $var = $key;
        $getarray = "'" . $var . "'";
        $recnumber = array($getarray);
        print_r ($recnumber);
        }

//way 2: assign to varriable 
foreach($decoZ as $array => $number)
foreach($number as $key => $value)
    if (in_array("$in", $number)) {
        $var = $key;
        echo "$var" . " ";
        }
?>

您只需重新映射记录即可

最后，你可以像这样抓住它们

$codes666 = $ids['666'];

给予

在每次迭代中，您都会覆盖数组
$recnumber=array（$getarray）

我宁愿遵循这个逻辑：

<?php
//user input
$in = "666";

$outputZ = '[
{"record_id_001":"1"},
{"record_id_002":"13"},
{"record_id_003":"666"},
{"record_id_004":"72661781"},
{"record_id_005":"8762"},
{"record_id_006":"666"},
{"record_id_007":"8762"},
{"record_id_008":"666"},
{"record_id_009":"8762"},
{"record_id_010":"8762"},
{"record_id_011":"666"}
]';

$decoZ = json_decode($outputZ, true);


// create empty array
$recnumber = [];
foreach($decoZ as $record)
{
    foreach($record as $key => $value)
    {
        // simply compare input with current value
        if ($value === $in)
        {
            // add the key to the previously created array
            $recnumber[] = $key;
        }
    }
}

var_dump($recnumber);

谢谢@Cid，这几乎是我所需要的全部，但是我需要进一步处理键，所以我需要将这个新数组中的所有值分配给一个变量。我该怎么做？（没有固定数量的结果-从2到5）。感谢动态创建的变量，如
$record\u id\u 003
，
$record\u id\u 006
等等？是的，我需要继续执行它们，因为它们是数据库中的id，我只需要提取那些记录，所以我需要它们作为$something。。。

    [1] => Array
        (

        (
