Can i somhow limit the function by definition?

[sangoku]

Hy i usually limit the variable when i pass a class by a variable like

 

protected function (class_name $class){

some crunching

}

 

So i limit the variable to only a class of that name....

 

 

My question is:

 

can i somehow limit on same way a variable to be only int or array or  string or somthing else...

 

side note i know how to check a variable if it any of given cind of data...  i am asking is it possible to do it the way it looks soo pretty XD

As far as I know this should also work:

 

 function (int $i) 

 

And it will do the check for you. If a non-int is passed in it should throw a warning or an exception. Only way to find out is to try it out

know about int ... string tough thinks it is  a class called string.... QQ

PHP doesn't support scalar type hinting. Currently there are plans for implementing scalar type hints in a future version of PHP, but exactly how it's going to work hasn't been decided yet.

You can also go the Java way of course, for example:

 

class Integer {
  private $value = 0;
  
  public function __construct($value) {
    $this->value = intval($value);
  }
  
  public static function parseInt($string) {
    return intval($string);
  }
}

$int = new Integer(5);
$intie = Integer::parseInt($_GET['value']);

class MyClass {
  public function __construct(Integer $int) {}
}
