PHP[OOP] - How to call class constructor manually?

Question

Please see the code bellow:

01. class Test {
02.     public function __construct($param1, $param2, $param3) {
03.         echo $param1.$para         


        

Answer 1

Note that if the constructor (__construct method) contains arguments passed by reference, then the function:

call_user_func_array

will fail with an error.

I suggest you to use Reflection class instead; here is how you can do so:

// assuming that class file is already included.

$refMethod = new ReflectionMethod('class_name_here',  '__construct');
$params = $refMethod->getParameters();

$re_args = array();

foreach($params as $key => $param)
{
    if ($param->isPassedByReference())
    {
        $re_args[$key] = &$args[$key];
    }
    else
    {
        $re_args[$key] = $args[$key];
    }
}

$refClass = new ReflectionClass('class_name_here');
$class_instance = $refClass->newInstanceArgs((array) $re_args);
