Check whether sessions work in php

checkSession.php

<?php

error_reporting( E_ALL );
ini_set( 'display_errors', 1);

if(!isset($_GET['action'])){
	die('Param is missing. Look at the <a href="https://gist.github.com/2995743">source</a>.');
}

switch($_GET['action']) {
	case "start":
		if(session_start() && $_SESSION['test']='test123'){
			echo 'Test session probably started successfully. Go <a href="mySessionTest.php?action=check">check</a>!</br>';
		}else{
			echo 'Starting a test session seems to have failed. Go <a href="mySessionTest.php?action=check">check</a>!</br>';
		}
		echo 'And some additional information:</br>';
		echo 'session.save_path : ' . ini_get('session.save_path') . '</br>';
		echo 'session.cookie_path : ' . ini_get('session.cookie_path') . '</br>';
		echo 'session.name : ' . ini_get('session.name') . '</br>'; 
		break;
	case "delete":

		session_destroy();
		echo "Test session deleted.";
		break;
	case "check":
		session_start();
		if(isset($_SESSION['test']) and  $_SESSION['test'] == 'test'){
			echo "Sessions seem to work. :-)";

Change line 33 to if(isset($_SESSION['test']) and $_SESSION['test123'] == 'test'){

and it will work :)

@matthewmalk248, I think you meant if(isset($_SESSION['test']) and $_SESSION['test'] == 'test123'){

Just for the record, I think it's highly amusing that some people are using this buggy snippet that I think I wrote when I was in middle school. @matthewmalk248
Do so at your own risk.

Nothing wrong with a nice simple script to copy paste and check session functionality on a fresh setup
