How to give object a name - php

Question

When I do the following:
$arUserStuff = array ('name' => 'username', 'email' => 'test#test.com');
$object = (object) $arUserStuff;
print_r($object);
The print function returns me the following:
stdClass Object ( [name] => username [email] => test#test.com )
How can I change std class object in let's say's User Object?

Answer 1

Create that class, then create an object of it:
class User {
public $name, $email; // public for this example, or set these by constructor
public function __construct( array $fields) {
foreach( $fields as $field => $value)
$this->$field = $value;
}
}
$object = new User;
$object->name = 'username';
$object->email = 'test#test.com';
Or, you can do:
$arUserStuff = array ('name' => 'username', 'email' => 'test#test.com');
$object = new User( $arUserStuff);
Now, from print_r( $object);, you'll get something like this:
User Object ( [name] => username [email] => test#test.com )

Answer 2

actually to do what you want, you should make it like:
$arUserStuff = new ArrayObject(
array (
'name' => 'username', 'email' => 'test#test.com'
)
);
to change the class name you need to create a new class.
It's a rather complex process but you can learn about it here:

Answer 3

Here's a generic function that converts an array into any type of object, assuming the fields are public
class User { public $name, $email; }
class Dog { public $name, $breed; }
function objFromArray($className, $arr) {
$obj = new $className;
foreach(array_keys(get_class_vars($className)) as $key) {
if (array_key_exists($key, $arr)) {
$obj->$key = $arr[$key];
}
}
return $obj;
}
print_r(objFromArray('User',
array ('name' => 'username', 'email' => 'test#test.com')));
echo "<br/>";
print_r(objFromArray('Dog',
array ('name' => 'Bailey', 'breed' => 'Poodle')));
Output
User Object ( [name] => username [email] => test#test.com )
Dog Object ( [name] => Bailey [breed] => Poodle )
I wanted to make a trait out of it but don't have PHP 5.4 installed to test it. This wouldn't require the fields to be public
trait ConvertibleFromArray {
public static function fromArray($arr) {
var $cls = get_called_class();
var $obj = new $cls;
foreach($arr as $key=>$value) {
if (property_exists($obj, $arr)) {
$obj->$key = $value;
}
}
return $obj;
}
}
class User {
use ConvertibleFromArray;
public $name, $email;
}
class Dog {
use ConvertibleFromArray;
public $name, $breed;
}
print_r(User::fromArray(array ('name' => 'username', 'email' => 'test#test.com')));
print_r(Dog::fromArray(array('name' => 'Bailey', 'breed' => 'Poodle')));
?>
