session & shell script

[juli]

Is it possible to use session in php when you have started in the same php file a background process by shell script? I couldn't.

I have a file login.php4 that looks like:
<?php
session_start();
session_register( "user_name");

//then I start a process:
system("/usr/local/bin/my_process > /tmp/my_script.$$ &", $res);

//then I redirect a browser to another page
//which is also using session:
header( 'Location: http://xxx/test.php4');
exit;
?>

All this doesn't work as long as session is active at least in one of the connected pages. The browser just hangs up.

Could you, please, help me?

I don't know if this is going to help you or not, but here is what I do when I use sessions.

I put this info at the beginning of the page where users enter data that is passed to a second page where the variables are registered/set:

<?
session_start();
session_unset();
session_destroy();

setcookie("PHPSESSID","","","/","");
?>

//other coding to collect data to send to second page.

I put this info at the beginning of the page where the variables are registered/set using the data from the previous page:

<?
session_start();
session_register('SESSION');
session_register('UserName');

//other variables here

if (!isset($SESSION)) {
$SESSION = array();
}

$HTTP_SESSION_VARS["UserName"]=$UserName;

//Are you missing the preceding step?
//other coding.

?>

I put this info in all subsequent pages that use data for this session:

<?php
session_start();
?>
