Simon Holywell shows how to quickly create the stdClass in PHP and populate it with properties and values, by casting an array to an object:
$x = (object) [
    'a' => 'test',
    'b' => 'test2',
    'c' => 'test3'
];
var_dump($x);
/*
object(stdClass)#1 (3) {
  ["a"]=>
  string(4) "test"
  ["b"]=>
  string(5) "test2"
  ["c"]=>
  string(5) "test3"
}
*/
A couple of things to keep in mind here are:
- In PHP, an associative array key have multiple same keys. If you cast such an associative array to object, the latest key will silently overwrite the value of the previous ones.
- The order of properties in the object will not necessarily match the order of keys in the associative array.
Very handy!
