PHP Variable ?

Anon

I know there is a way you can easily find out with php from which url the visitor came to your site, but i can't remember the name of the variable. Please tell me what its exactly name and how to use it in a right way.

Thanks in advance

$HTTP_REFERER

oh should have said that you can get a full list of all available variables by using phpinfo() just run this file.

<?php phpinfo(); ?>

Mark.

i can't just say echo $HTTP_REFERER ;

It does not work, so how can i use it to echo the url the user came from ?

You should be able to just echo the value.
have you tried the phpinfo() it will tell you what you should be getting from the HTTP_REFERER.

Mark.

did not find any entrie in the information the phpinfo() gave me about the variable. Could that mean my server does not support this kind of variable to be used ?

try this.

In one file say test.html put the following

<A href="test.php">Click here</A>

</BODY>

and in test.php put

<?php

echo $HTTP_REFERER;

phpinfo();

it works on my machine. you may need to adjust your php.ini file.

first of all, you need to be coming from another page to be able to use $HTTP_REFERER. so first make a plain html page with a link on it to your script. then, click the link to go to your script. just make the script real simple to test:

<?
print $HTTP_REFERER;
?>

if that doesn't work, try this:

<?
$ref = getenv($HTTP_REFERER);
print $ref;
?>

make sure that you are starting from the html page and clicking on the link to get to the script or the variable will be empty.

if (isset($HTTP_REFFERER))
{
print ("You came from: $HTTP_REFFERER");
} else {
print ("You typed in the URL and didn't come via a link.");
}
