は、私は、配列を検索し、レベルが存在し、値が何であるかどうかを確認したいと思いますインデックスの は、私は次のことを試してみました：

$number = array_column($array, 'level'); 
$found_key = array_search('2', $number); 

       But I get no response . 

私は、配列を確認し、レベルが存在し、それが保持している値が何であるかどうかを確認する方法上の任意の助けを？

Answer 1

あなたはそのようなもので、あなたの配列をフィルタリングすることができます。

$filterBy = '2'; 
$newArray = array_filter($array, function ($var) use ($filterBy) { 
    return ($var['level'] == $filterBy); }); 

print_r($newArray); 

$names = array_column($newArray, 'id'); 

print_r($names); 

Answer 2

それがオブジェクトであるとして、あなたがそれらにそれらのアレイベースの機能を使用したい場合、あなたは配列型にそれらをキャストする必要があります：

<?php 
$x = new stdClass(); 
$x->y = 'test'; 
$x->z = 'more testing'; 

$array = (array) $x; ----> Is now an array. 
?> 

（配列） - 配列へのキャスト

より良い理解を得るためにthisおよびを参照してください。

Answer 3

あなたはこのようforeachループ

を使用することができます。

foreach ($array in $key => $value){ 
    if($value["level"] != ''){ 
     echo $value["level"]; 
    }  
}
