Resolved referer array

[durangod]

Question, im trying to grab just the root of HTTP_REFERER.

The below will work but sometimes RERERER is like this

http://www.mysite.com/whatever/whatever.html

And of course in that case the key exist will be false. So whats the best way to limit REFERER to just root.

PHP Code:

$ref = $_SERVER['HTTP_REFERER'];

$ok_array = array('http://www.mysite.com', 'www.mysitel.com', 'mysite.com');
 
if (array_key_exists($ref, $ok)) 
{
  //do something 
} 


I do understand that REFERER could be blank for non referrers but that will be fine, i am trying to hardcode just my site as permitted, the rest can do what they want.

i guess i could use SERVER_NAME right

Thanks.

No, server name will be your server.
You want to use parse_url():

PHP Code:

if (!empty($ref))
{
    $domain = parse_url($ref, PHP_URL_DOMAIN);
    in_array($domain, $ok_array))
    {
        // its in the array
    }
} 


so with your example, that would create $domain with the value of "www.mysite.com"
