How can I initiate session_start(); before every static method is called in PHP?

Question

I'm trying to learn OOP in PHP and I'm making a class with static methods.I tried the code below but the session_start(); will not work because the methods are static and no object is getting instantiated.Do you know any solution to this problem?

<?php

class Session{

    public function __construct(){
        session_start();
    }

    public static function set($data){
        foreach ($data as $key => $value) {
            $_SESSION[$key] = $value;
        }
    }

    public static function get($key){
        return $_SESSION[$key];
    }

}


Session::set(array(
    'mySessionKey' => 'mySessionValue'
));

Answer 1

I would really recommend you to add this to the top of the files where you operate with sessions:

if(session_status() == PHP_SESSION_NONE) session_start();

This starts your session if it did not already start.

Go to the php.net documentation to learn more about the super global $_SESSION .

Hope this helps.

Slight change to @Bluedayz answer ...

<?php

class Session {

    public static function set($data) {
        if (session_status() == PHP_SESSION_NONE) {
            session_start();
        }

        foreach ($data as $key => $value) {
            $_SESSION[$key] = $value;
        }
    }

    public static function get($key) {
        return $_SESSION[$key];
    }

}


Session::set(array(
    'mySessionKey' => 'mySessionValue'
));
