[Resolved] creating html link

[perpetualshaun]

I could of sworn I saw a function that will do this on php.net before, but I can't find it today when I could really use it on a project.

Let's say I have a long block of text like this:

$string = "kjlakf afjlakf afj afklja f jkalfja faf akfjal f www.yahoo.com akdjflj afj afkj ff affjafk fa jfakjaf af faj alkj ffaaf fa jlkafj"

Is there a function out there somewhere, that someone far wiser than I w/ regular expressions, has already written to pull out the www.yahoo.com and put the <a href></a> tags around it?

Thanx

If it is rather easy to extract anything that begins with "www", it's more difficult to tell where it ends, unless you hardcode all possible domain extensions .com,.org,.net....
Supporting only the two domain extensions .com and .net, the Regexp would be something like this :

.(www.[.com|.net]).*

and you can just extract the 1st capturing group.

Now a detail : how to do it in PHP 😃

taking your example

$mystring = "blablablawww.yahoo.comblabla";
$mypattern = ".*(ww.*[.com|.net]).*";
if (ereg($mypattern,$mystring,$regs)) {
echo "THe URL : ".$regs[1];
}
else {
echo "Pattern not found";
}

something like that (not tested).

hope it helps

EDIT : removed the 3rd "w" from the pattern to avoid automatic formatting.
