on one of my website, i kept getting this error on a new script i just installed on a brand new linux server provided by Webune.com which i just leased a dedicated server from Webune.com

this was the errors:
Notice: Undefined variable: leftLinks in /var/www/home/shop/script/header.php on line 124

Notice: Undefined variable: q in /var/www/home/shop/script/header.php on line 138

Notice: Undefined variable: welcome in /var/www/home/shop/script/header.php on line 148

I was trying to figure out how to fix this error, i contacted the support team at Webune and they were able to give me an answer quickly.

so just in case it happens to me in the future, i can have this tutorial guide to remind me on how to fix this PHP error. or if anyone has the same problem they can benefit from the support team at Webune Web Hosting.

so to fix this error you need to login into you Webune Dedicated Server. If you are not a Webune cusotmer, make sure you are having this problem on a linux server like Red Hat, Fedoar, Centos etc..

To start login as root using a SSH connection to your linux shell prompt.

make a backup of the php.ini file with this command:

CODE:

cp etc/php.ini /etc/php.ini.backup

then open the php.ini file with a text editor, i wll be using nano which comes with linux, you can also us VI, but i like nano better. i will open it using nano with this command:

CODE:

nano /etc/php.ini

now look for this line in the php.ini file:

CODE:

error_reporting = E_ALL

NOTE: you may have something different set for the error_reporting , just make sure you make the changes on the line without a semi-colon because a semi-colon at the begining of the line mean its a comment

So now change it to:

CODE:

error_reporting = E_ALL & ~E_NOTICE

Save your changes and then restart you Apache server for the changes to take affect witht his command:

CODE:

/etc/init.d/httpd restart

once your Apache server restarts, go back to the page where you were getting this error and refresh the web page and you should not see this error anymore.

Hope this help. Please provide any feed back or comments you have by submitting your reply at the bottom of this page. thanks

Sounds like you need to initialize your variables. Look at initvar()

use either "if(!empty($fu) or "if(isset($fu[' instead of "if $fu{}" or "if $fu['#bar']{}"

- at - Alex totally! I am angry using WordPress plugins from developers that never check to make sure the property/object is available! Even wordpress itself is falls foul of this. I have "fixed" the wordpress install I have but won't deploy it. Might do an article about it!

Very Thanks!!!!!

This is absurd! You are not fixing the problem, you are simply hiding it - the error still exists AND in many cases would leave a site open vulnerable to attacks!

You didn't mentioned your code. Any way those are notice, you can ignore it by writing error_reporting(0); at the top of your page.

Notice: Undefined variable: articleheading in /home/mm652/public_html/i on line 37

David Thu Aug 19, 2010

You didn't fix the problem, you just found a way to ignore it. You still have three undefined variables.

sorry guys but just switching off the error message doesnt fix an php-error.
it just hides it in apache logs

works great! why i have to have an error everytime a php variable isn't defined yet i dunno. even if(defined($var)){} or if($var == ""){} don't work without your fix.

// error_reporting = e_all
error_reporting = e_all & ~e_notice
