Converting posted URL to html link

[paulbenjaminturner]

Hi,

 

Apologies if this has already been addressed, but I've spent quite a while searching and can't seem to find an answer.

 

I'm looking for a function to be used on my forum which will automatically locate a URL that a user has posted and convert it into an html link.

 

Thanks very much,

 

Paul

$url = $_POST['url'];
print (create_url($url));

function create_url ($url) {
  if (!stristr ($url, "http://"))$url = "http://".$url;
  $httplink = "<a href='$url'>$url</a>";
  return ($httplink);
}

 

Something like that?

Hi

 

Thanks for your reply. That would work fine if I knew the entire URL, but I need a function that will locate it within a string that could contain hundreds of other words.

 

Thanks,

 

Paul

Is the url located in a db or something?

Then you need to use a regular expression using preg_replace. Look up url matching regular expressions. There might be more answers in the regular expressions forum.
