How to convert array object to object array in php

During the PHP development process, sometimes it is necessary to convert an object represented by an array into an object array so that it can be manipulated using object-oriented methods. This article explains how to implement this feature.

First, we assume that there is an object represented by an array, similar to the following:

$user = [
    'id' => 1,
    'name' => 'Jack',
    'age' => 28,
];

This object represents a user and contains the user's ID, name and age attributes. Now we need to convert it into a User object so that we can manipulate it using object-oriented methods.

We can define a User class that contains ID, name and age attributes, and define the corresponding constructor:

class User {
    public $id;
    public $name;
    public $age;

    public function __construct($id, $name, $age) {
        $this->id = $id;
        $this->name = $name;
        $this->age = $age;
    }
}

Then, we can write a function to convert objects represented by arrays Into a User object:

function arrayToObject($array) {
    $objectArray = [];

    foreach ($array as $item) {
        $user = new User($item['id'], $item['name'], $item['age']);
        array_push($objectArray, $user);
    }

    return $objectArray;
}

This function accepts an object represented by an array as a parameter, and uses a foreach loop to traverse each item in the array. For each item, it creates a new User object and adds it to an array of objects. Finally, it returns an array of objects.

Now, we can use this function to convert an object represented by an array into an object array:

$users = [
    [
        'id' => 1,
        'name' => 'Jack',
        'age' => 28,
    ],
    [
        'id' => 2,
        'name' => 'John',
        'age' => 32,
    ],
    [
        'id' => 3,
        'name' => 'Lily',
        'age' => 25,
    ],
];

$objectArray = arrayToObject($users);

This code converts each item in the users array into a User object, And store the result in objectArray array. Now, we can use object-oriented methods to operate this object array:

foreach($objectArray as $user) {
    echo $user->name . ' is ' . $user->age . ' years old.';
}

This code will traverse each User object in the objectArray array and output the name and age of each user.

To summarize, converting an object represented by an array into an object array allows us to use object-oriented methods to operate it, making the code more concise, readable, and maintainable. We can easily convert an object represented by an array into an array of objects by defining a class and corresponding constructor, and writing a function that converts the array into an object.
