How to add a new method to a php object on the fly?
Solution 1:
You can harness __call for this:
class Foo
{
public function __call($method, $args)
{
if (isset($this->$method)) {
$func = $this->$method;
return call_user_func_array($func, $args);
}
}
}
$foo = new Foo();
$foo->bar = function () { echo "Hello, this function is added at runtime"; };
$foo->bar();
Solution 2:
With PHP 7 you can use anonymous classes, which eliminates the stdClass limitation.
$myObject = new class {
public function myFunction(){}
};
$myObject->myFunction();
