I am having problem with PHP4 session variables. I think I misunderstood how
they work, and I can't see what I'm doing wrong. Any help would be
appreciated. I am using the version from EasyPhp 1.1.1.
Below is a short example to explain my problem. I've got two php scripts.
'test1.php' which start a session, set a variable $sess and register it as a
session variable. It then redirects to 'test2.php' which only displays
session variables and switches $sess[var1] between true and false on each
call.
With the code in example, I retrieve the variable set by 'test1.php' on
'test2.php', but $HTTP_SESSION_VARS['sess']['var1'] is always true.
With the same code, If I set register_globals to off in my php.ini, I get
the opposite. I never retrieve the variable set by 'test1.php' on
'test2.php', but $HTTP_SESSION_VARS['sess']['var1'] is switches correctly.
What is wrong in this code ??
If I replace
session_register('sess'); in 'test1.php'
by
$GLOBALS['HTTP_SESSION_VARS']['sess'] = $sess;
and set register_globals to off everything works. Someone could explain to
me why ??
Best regards,
Nicolas
File test1.php
<?
function initSessionVar()
{
global $sess;
// initialise sess variable for the new session
$sess = array();
$sess['user'] = "test";
$sess['var1'] = true;
session_register('sess');
}
session_start();
initSessionVar();
header('Location: http://localhost/test2.php');
exit;
?>
File test2.php
<?
session_start();
echo gettype($HTTP_SESSION_VARS['sess']) . "<BR>";
echo $HTTP_SESSION_VARS['sess']['user'] . "<BR>";
echo ($HTTP_SESSION_VARS['sess']['var1'] ? "true" : "false");
if ($HTTP_SESSION_VARS['sess']['var1']){
$HTTP_SESSION_VARS['sess']['var1'] = false;
}
else{
$HTTP_SESSION_VARS['sess']['var1'] = true;
}
?>
