please help!session_start() problem!

eosinophil · August 24, 2009

Hello. I'm new to this forum, so maybe the admins will forgive me if I do anything wrong.

My problem is this :

I have a working piece of code, with no session! But when I try to add this session_start() function I get errors like

Warning: Invalid argument supplied for foreach() in I:\raul\list.php on line 137

Warning: Invalid argument supplied for foreach() in I:\raul\list.php on line 163

Fatal error: Cannot use string offset as an array in I:\raul\list.php on line 173

This works when I comment the line session_start();

I know that it should be at the beginning of the file with no extra chars in front of and etc. Anyways the function session_start() does not throw any errors or warnings. The problem is in list.php which does not even have the session_start() in it!! So what the heck does this function do exactly?

Thank you ! :'(

Post your code, especially the ones generating the errors.

eosinophil · August 24, 2009

so nobody is going to answer me ?

or maybe you could solve this one : http://codingforums.com/showthread.php?t=88006 ?

any help would be greatly appreciated !

I think the question would be : what the &^%$ does this session_start() _exactly_ do ?

why does it work with no session_start()? the code has nothing to do with the session. just with $_REQUEST. I'm so new to php so I have no clue about this stuff.

kenrbnsn · August 24, 2009

Don't be so impatient.

The only "session_start()" in the code you posted is commented out, so this is not the code that is giving you the errors.

If you're unsure of what it does, read the manual entry for session_start

Ken

eosinophil · August 24, 2009

ok! I have this file _data.php

<?session_start();

//error_reporting(1);

error_reporting(6143);

ini_set("display_errors", true);

foreach ($_REQUEST as $k=>$v)

$$k=htmlspecialchars($v);


?>

If I comment session_start() it runs ok, but if not the first post's warnings and fatal error appear!

Please help !!!

Thanks , I read the manual, but I feel something is missing. This function has to be doing something else or this is very strange.
