Php
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
*/
$arr = array('senderId' => 10);
$obj = (object) $arr;
echo $obj->senderId; // 10
stdClass
In PHP the default object is of stdClass type..
/**
* stdClass is the default PHP object.
* stdClass has no properties, methods or parent.
*
* It does not support magic methods.
* It implements no interfaces.
*
* When you cast a scalar or array as Object, ...
* you get an instance of stdClass.
*/
$obj = (object) array(); // OR
$obj = new stdClass();
$obj->key1 = "value1";
$obj->key2 = "value2";
var_dump($obj);
/*
object(stdClass)[1]
public 'key1' => string 'value1' (length=6)
public 'key2' => string 'value2' (length=6)
*/
