Parentheses
Type casting in PHP works much as it does in C.
/**
* The name of the desired type is written ...
* in parentheses before the variable.
*/
$A = array(1, 2, 3);
$B = (string) $A;
var_dump($A); // array(3) { ... }
var_dump($B); // string(5) "Array"
Object
You can call an array item like object property if you type cast array to object.
/**
* Array to Object type casting
*/
$A = array('senderId' => 10);
$B = (object) $A;
echo $B->senderId; // 10
stdClass
In PHP the default object is of stdClass type.
/**
* stdClass()
*
* Is the default PHP object
* Has no properties, methods or parent
*
* When you cast an array as Object,
* you get an instance of stdClass
*/
$A = (object) array(); // OR
$A = new stdClass();
$B = (object) [1, 2];
$B->x = "3";
$B->y = "4";
print_r($B); // stdClass Object( 0=>1, 1=>2, x=>3, y=>4)
