I'm getting the following error PHP Notice: Undefined index: HTTP_REFERER in C:\Inetpub\cgi-bin\search5.php on line 168 on first call..
i'm just trying to get the value of this
$_SERVER['HTTP_REFERER']

any solution for this?

Thanks..

this notive means that the key 'HTTP_REFERER' is not set in the $_SERVER array. Try using this code to see if the key exists, and then start doing stuff with it:

PHP Code:

if(isset($_SERVER['HTTP_REFERER'])){
  // do stuff
}

Your error reporting is not set to its default. Usually E_NOTICEs are not shown.

Try either setting this at the top of your script:

PHP Code:

error_reporting(E_ALL ^ E_NOTICE); 

Or try changing the value in your php.ini file, or try using .htaccess if you don't have access to it.

Umm... While the above posts are OK, they don't answer your question 100%. On the first load of your page (when you open the browser and type the address or jump there form a bookmark/ICQ/newsreader/email) there is no referrer, hence that entry in the $_SERVER array is undefined.

Empty referrer can also be the result of user's browser not sending it (ie, the user has turned off referrers in his browser).

I got the same error message after switching my PHP scripts from Apache to IIS.
Problem solved by adding that code in the master page , thanks!

*hm..yeah I am replying a post that is a year old, but problem solved =)*

Everyday I'm reading that the people are saying that "this mysterious line of code has solved my problem, thanks!"
As an important note you might want to know that this error_reporting() thing!! is not able to solve any problem. that's just hiding the error echos.

In any "echo" case, such as this, we have to check if the variable is set or not! then we can decide more obviously.

cheers,

I added this code and the notice error message is not showing anymore. The thing is it wasn't showing before until I tried installing and uninstalling Zend. And how come it is not showing in my other computer (Linux OS) where I have not installed Zend? Is Zend the culprit of this notice error message?

The culprit of that message is the programmer itself. It means you forgot to declare something before you accessed it. Like using a variable that you haven't declared yet.

The reason why you're not seeing those notices any longer is because, using the code Nico posted, notices are disabled. It's better not to disable them, but to fix them.
