Pass arguments from array in php to constructor

Question

Normally, if I want to pass arguments from $myarray to $somefunction I can do this in php using

call_user_func_array($somefunction, $myarray);

However this does not work when the function one wishes to call is the constructor for an object. For fairly obvious reasons it does not work to do:

$myobj = new call_user_func_array($classname, $myarray);

is there something fairly elegant that does work ?

Answer 1

You can use the Reflection API:

• ReflectionClass::newInstanceArgs — Creates a new class instance from given arguments.

Example:

$reflector = new ReflectionClass('Foo');
$foo = $reflector->newInstanceArgs(array('foo', 'bar'));

Answer 2

Or, you could just pass the array directly?

$myObj = new $classname($myArray);

And read the elements of the array inside the method as if they are parameters to that method (the constructor in this case).
