External Variables Inside A PHP Class...

hello there... regarding the declaration of an external variable inside a php class.. it is not working with me... for example :

class name
  {
  public $name = $_POST["name"];
  }

i get an error... i tried using : var , protected, private.. but nothing is working... so ?

You cannot initialise variables with variables in such a way. Use the the constructor instead:

class name
{
    private $name;

function __construct()
{
    $this->name = $_POST["name"];
}
}

well i don't want to use the constructor function, i was just wondering if there's another way of delcaring them... thanks anyway

You can use that syntax with constants, e.g.,

class name
{
    private $name = 'daredevil14';
}

yeah... i do know that... thanks anyway 🙂

As stated in the manual, "The default value must be a constant expression, not (for example) a variable, a class member or a function call." Thus, the only way you can set it to a non-constant expression is via direct setting of its value from the calling code (if it is public) or else via a method. The only way to make it a "pseudo-default" value is to make it part of the constructor, as LL originally suggested to you.
