从std类多维数组php中提取完整数组

我正在做一个考试系统，为了得到正确的结果，我遇到了一个问题。 我希望这个结果来自与问题ID 466匹配的答案数组

(
[id] => 234
[firstChoice] => 2
[choice] => 2
[marked] => 
[strikethrough] => Array()
[highlights] => 
[guessed] => 
[difficulty] => easy
[numTimesChanged] => 
[timeElapsed] => 36
)

我有这种类型的std类数组。 我也有同样类型的问题数组

Array(
[0] => stdClass Object
    (
        [id] => 234
        [firstChoice] => 2
        [choice] => 2
        [marked] => 
        [strikethrough] => Array
            (
            )

        [highlights] => 
        [guessed] => 
        [difficulty] => easy
        [numTimesChanged] => 
        [timeElapsed] => 36
    )

[1] => stdClass Object
    (
        [id] => 466
        [firstChoice] => 3
        [choice] => 3
        [marked] => 
        [strikethrough] => Array
            (
            )

        [highlights] => 
        [guessed] => 
        [difficulty] => easy
        [numTimesChanged] => 
        [timeElapsed] => 5
    )
)

试试这个：

$result = null;
foreach($array as $value){
    if($value->id == 466){
        $result = $value;
        break;
    }
}

如果您的ID不唯一，您可以使用

解决方案：

<?php

$array = json_decode('[{"id":4,"data":"data1"},{"id":14,"data":"data41"},{"id":14,"data":"data14"}]');

$idSearched = 14;

function filter($item){
    global $idSearched;
    return $item->id === $idSearched;
}

$res = array_filter($array, "filter");
print_r($res);

您尝试过什么？如果可能，我建议在数据生成时将id设置为密钥。
