[PHP] $_SESSION var sometimes set, sometimes not

[Anthony Whipple]

Hi,

The following code sometimes produces output indicating that the session
variables have been set, and sometimes is says that they have not been set.
Unfortunately the server is not mine to configure, but if there is a problem
with it, I can get in touch with the right people.  Is the script properly
written?  Is it a server problem?


html
head
 titleTest stuff.../title
/head
body

?php
session_start(); // enable session level global variables

if (isset($_POST['action'])  $_POST['action'] == 'sub1' ) sub1();
else {
session_unset(); // all variables start fresh here
$_SESSION['test']='HERE I AM!br';
echo $_SESSION['test'];
print_r ($_SESSION);
}

function sub1()
{
echo sub1 routinebr;
print_r ($_SESSION);
if ( isset($_SESSION['test']) )
echo $_SESSION['test'];
else
echo 'variable not setbr';
}


///
?

form action=?php echo $_SERVER['PHP_SELF']; ? method=POST
select name=sub1
option sub1 /optionbr
/select
input type=hidden name=action value=sub1
input type=submit name=submit value=go
/form

/body
/html

I just tried that.  It made no change.  Still sometimes works, sometimes
doesn't.  It's on the order of clicks.  It may work three times in a row,
then fail a couple times.  It's very strange.

 This shouldn't work at all. You need to have session_start() before any
 HTML or output. The beginning of your file should be

 ?php session_start(); ?
