Session varible in virtual Linux Instance IBM S390

szgbtxgs

I just move the web pages from windows to linux instance. But the session
variable doesn't work. And I found that in the \tmp directoy, it has
sess_****(MD5) file,but with empty contents,just 0 byte.

BTW, the code works well in windows and Linux (not virtualhost) in my computer.

How to fix it?

Thank you

Well there can be many factors to why it doesnt work and more then likely im not going to guess the one that will work. If you could shed the light by showing some of the code you are using would help.

szgbtxgs

the first file: index.php

<?php session_start(); ?>
<html>
<body>
.
.
(html code)

<?php
echo " session" .$SESSION['searchsql'];
if (isset($SESSION['searchsql'])) unset($_SESSION['searchsql']);

.
.
.
?>
</body>
</html>

The second file:search.php

<?php session_start(); ?>
<html>
<body>
.
.
(html code)
<?php
$searchsql="select * from events ";
$_SESSION['searchsql']=$searchsql;
header('Location:index.php');
?>
</body>
</html>

szgbtxgs

the result from index.php
it printed,

session

(the value wasn't passed from search.php)

Then I commented the statement : if (isset($SESSION['searchsql'])) unset($SESSION['searchsql']); and bowsered the web page-search.php again. I found it created the file: sess_***(MD5) in the \tmp (session.save_path) , but with 0 byte. It seemed that it has problem to write the data to the file.
What's wrong with it? It just happened in the virtualhost. when I moved the web pages in the other linux system, eg, my computer's linux system, it has no such problem. The webpages work well.
