When doing echo $_SERVER['HTTP_REFERER'] I see the information:

[a href=\"http://www.koenvissers.nl/survey/survey.php?uid=14482e0bec0181&linkcode=Ef0004\" target=\"_blank\"]http://www.koenvissers.nl/survey/survey.ph...linkcode=Ef0004[/a]

How can I extract Ef0004 from $_SERVER['HTTP_REFERER']?

Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)

thx...

Solved it:

$lnkcod = str_replace("http://www.koenvisse...0181&linkcode=", "" , $_SERVER['HTTP_REFERER']);

This is not going to work if there are any small differences in the URL.
You should use true regex.

If you tell me what you expect linkcode to be (what is it's length? alphanumeric only? is it always in the end of the URL) I can give you a regular expression...
