Warning: Unknown: Your script possibly relies on a session side-effect which existed

I have this warning at the botom of my home-page


Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0

Plz advise to remove this.
Thanks

 

do NOT turn off session.bug_compat_warn
it states clear that in all versions below PHP 4.2.3 extensions does not consider global variables as a source of data
hope that helps

 

Sorry but no it dont help,as ime somewhat a noob with php.
I need a answer for this problem that a nooby like me can fix.
Thanks

 

some1 must have a fix for this

 

Upgrade to a newer version of PHP.

 

upgrade and make sure ur server/hosting is set to php enabled

 

In your php.ini files set session.bug_compat_warn = Off
It sounds like it's a register_globals issue, which the 'jist of it means if the url is like index.php?var=val, then it makes the variable $var and gives it the value 'val' (when register globals is on), otherwise you use $_GET['var'] to access the data, which is more proper and more secure, it just sounds to me like it's something similar but for sessions, I've never heard of it, but then it's really old and antiquated PHP and it was mainly done by lazy or inexperienced coders.

 

Yay! I'm obviously lazy - I'm getting this error in my error log too!

The trouble is - it's not obvious which file is causing the error?

It seems to be a harmless error as I've had no problems with any of my website, but yet this error keeps cropping up.

Oh well... as long as it's not causing a noticeable error - I'm happy!

 

I solved this error.And thank all for your replys and help.

The fix.
Make a new file called ini.php
add this code

session.bug_compat_42 = 1
session.bug_compat_warn = 0

it works for my site.I have atached the file to this thread if any1 need it

 

Thanks! I was also looking for a code to deactivate this unnecessary warning. Your code worked fine.

 

Hi Goldgansta,
can you plz tell me after creating the ini.php file, where shall i place ? Does it need to be include in the respective file ? or the folder...
Thanks for your quick help

 

Place the file inside your public_html folder.
It should work if not i can have a look for you!

 

I found this by trying to resolve the issue of the error message of:

Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled.

After reviewing these post and attempting to resolve the issue stated above it did not work for me. Here is how I finally resolved the issue.

added these two lines of code to my .htaccess file in the root directory

php_flag session.bug_compat_42 1
php_flag session.bug_compat_warn 0

 

Yes that option also works if you hosting company does not allow custom ini.php

Thanks for adding that fix it will come in handy for those situations..

 

In my opinion all hosting companies should let customers customize their php.ini , I do not understand why they are not allowing their clients to use and modify php.ini...

 

I have had this problem in the past, it means you've produced content or you have spaces before <?php or session_start(). Since session_start() works with cookies, and cookies works with headers, they must be before any sort of content is produced.

 

I had the same error:
Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0.

on code like this:

<?php
$currentCatId = $_SESSION['currentCatId'];

if (isset($_GET['catId'])) {
$currentCatId = $_GET['catId'];
}

.......

for ($c=0;$c<count($categories);$c++) {

if (isset($currentCatId)) {

if ($categories[$c]['category_id'] == $currentCatId) {
echo 'string';
}
}
}
?>



and solved the error by changing my code to this:

<?php

if (isset($_GET['catId'])) {
$_SESSION['currentCatId'] = $_GET['catId'];
}

.......

for ($c=0;$c<count($categories);$c++) {

if (isset($_SESSION['currentCatId'])) {

if ($categories[$c]['category_id'] == $_SESSION['currentCatId']) {
echo 'string';
}
}
}
?>


"isset" doesnt seem to like non-global variables.

 

I had this Warning when I used as a session index the same name for a global PHP variable, even if I used them as separate variables.

global $foo;
$_SESSION['foo']

This gave me the warning. I renamed one variable and warning got away.

global $foo;
$_SESSION['_foo']

 

Hi all, i also faced this problem. I am using XAMPP so where should I put these??

session.bug_compat_42 = 1
session.bug_compat_warn = 0

 

Hi, this is my php.ini. how I can it so that it won't come out the warning?? thanks~
