php global excution inside the class

PHP's define("CONSTANT", "Hello world."); is global function which is you can call it even if your inside the class or function. I have example below and let's say inside the class I declare a global variable supposed to be like private global $allForm;

my question how can i call the $this->allForm inside validate() without embedding the $this->validate() inside the __construct?

$authentication = new authentication("1", "nanat"开发者_如何转开发, "amew", "yes" ); // declared define constant

class authentication extends mySession {
    private $allForm; //variable

    public function __construct($submit, $user, $password, $remmeber) {
        $this->allForm = array('giSub' => $submit, 'giUser' => $user, 'giPas' => $password, 'giRemmeb' => $remmeber); //execute
       // $this->validate(); //not execute
   // $this->validateOne(); //not execute
   // $this->validateTwo() //not execute
    }

    private function validate() {
        var_dump($this->allForm); // return null
        // statement...
    }

private function validateOne() {
        var_dump($this->allForm); // return null
        // statement...
    }

private function validateTwo() {
        var_dump($this->allForm); // return null
        // statement...
    }


}

what i want is.. is this possible?

class authentication extends mySession {
    private $allForm; //global variable.. 


    public function __construct($submit, $user, $password, $remmeber) {
        $this->allForm = array('giSub' => $submit, 'giUser' => $user, 'giPas' => $password, 'giRemmeb' => $remmeber); //execute
    }

    private function validate() {
        var_dump($this->allForm); // return true
        // statement...
    }

private function validateOne() {
        var_dump($this->allForm); // return true
        // statement...
    }

private function validateTwo() {
        var_dump($this->allForm); // return true
        // statement...
    }


}

You aren't required to immediately call $this->validate() from the construct. If you're populating $this->allForm in the constructor, the value will continue to exist when you call class methods. Remove that $this->validate() from __construct() and you can call the validate() method manually:

$authentication = new authentication( "1", "nanat", "amew", "yes" );
$authentication->validate();

Based on the way you have asked this question, that's the best answer I can provide.

$allForm is declared as a private member of class authentication. This means that you can only access $allForm from code that is inside class authentication. If you want to access $allForm from outside the class, you'll need to declare it as public.

You can apply the same reasoning to the validate() method as well. If you want to be able to call it from outside the class, then just declare it public:

class authentication extends mySession {
    public $allForm;

    ...

    public function validate() {
       ...
    }
}

Now you can do stuff like this....

$authentication  = new authentication("1", "nanat", "amew","yes" );
$authentication->validate();

OR

$authentication->allForm = array(....);
