对数组属性的访问包含laravel中的json格式元素

Question

suppose I have an Array like this :

$myArray =
[
    {
        "id": 86,
        "name": "admin/login"
    },
    {
        "id": 87,
        "name": "admin/logout"
    },
    {
        "id": 88,
        "name": "admin/desktop"
    }
]

Each element of array has json format. and now I want to get name of element that have id of 87 for example.

Firstly How can I found that is there element with this id then get name property of that?

Answer 1

Decode JSON string into array. Then use Laravel's array_first method.

<?php
$myArray = '[{"id": 86,"name": "admin/login"},{"id": 87,"name": "admin/logout"},{"id": 88,"name": "admin/desktop"}]';

// Decode into array
$array = json_decode($myArray, true);

// Find item with correct id
$result = array_first($array, function($key, $value){
  return $value['id'] === 87;
}, false);

if ($result) {
    echo 'Item found, it\'s name is: '.$result['name'];
}

If you have id you like to find in variable, you have to use use construct.

// ID to search for
$searchID = 87;

// Find item with correct id
$result = array_first($array, function($key, $value) use($searchID){
  return $value['id'] === $searchID;
}, false);
