How to call the constructor with call_user_func_array in PHP

You can use reflection like:

$reflect  = new ReflectionClass($class);
$instance = $reflect->newInstanceArgs($args);

As of PHP 5.6.0, the ... operator can also be used for this purpose.

$instance = new $class(...$args);

if(version_compare(PHP_VERSION, '5.6.0', '>=')){
    $instance = new $class(...$args);
} else {
    $reflect  = new ReflectionClass($class);
    $instance = $reflect->newInstanceArgs($args);
}
