Re: Objects and sessions

[Shen Kong <shenkong@xxxxxxx>]

Hi, your code my be this , you must use session_start() first:
<?php
session_start ();
class SessionTestC {
   protected $value;

   function __construct ( $val ) {
       $this->value = $val;
   }

   function GetValue () {
       return $this->value;
   }
}

if ( isset ($_SESSION['TestObj'])) {
   echo 'Session Test is set to: '.$_SESSION['TestObj']->GetValue().'<br>';
} else {
   echo 'Session Test was not set.<br>';
   $_SESSION['TestObj'] = new SessionTestC ( 'This is a test' );
   echo "<a href='".basename($_SERVER['PHP_SELF'])."'>Click here.</a><br>";
}

?>
