How do I bust up a URL into real links?

bartertown

I have a form input to a discussion forum and I would like to make all of the links hyperlinks automatically so people don't have to put in the HTML code. I did (stole) this in PERL and here's what it looks like:

#!/usr/bin/perl
use strict;

print my $text = "Reckoning is at http://reckoning.org/.\n";

my $urls = '(http|telnet|gopher|file|wais|ftp)';
my $ltrs = '\w';
my $gunk = '/#~:.?+=&%@!-';
my $punc = '.:?-';
my $any = "${ltrs}${gunk}${punc}";

$text =~ s{
\b
(
$urls :
[$any]
+?
)
(
?=
[$punc]*
[^$any]
|
$
)
}{<a href='$1'>$1</a>}igox;

print $text;

How do I do the same in PHP? I am having 0 luck so far.

Sorry, the tabs didn't go through as hoped. I hope you can still read it.

I found this on the php.net site, user comments under preg_replace():

$message = preg_replace("/((http(s?):\/\/)|(www.))([\w.]+)/i", "<a href=\"http$3://$4$5\" target=\"_blank\">$2$4$5</a>", $message);

There might be a cleaner way to do it, but this is worth a shot.

Thanks for your help but it doesn't seem that works, this doesn't either:

$message = preg_replace("/((http(s?):\/\/)|(www.))([\S.]+)/i",
'<a href="http\3://\4\5" target="_blank"
class="whitebglinkUN">\2\4\5</a>', $message);

Anyone want to give 30 seconds of their sheer brilliance and let me know what I'm doing wrong?

<?php

$message = "Hello my name is mr burns, i believe http://www.bartertown.org/ you have a letter for me";

$message = preg_replace("/((http(s?):\/\/)|(www.))([\w.]+)/i", "<a href=\"http$3://$4$5\" target=\"_blank\">$2$4$5</a>", $message);

$message = preg_replace("/((http(s?):\/\/)|(www.))([\S.]+)/i", '<a href="http\3://\4\5" target="_blank" class="whitebglinkUN">\2\4\5</a>', $message);

$message = preg_replace("(([url]http://[/url]|[url]ftp://[/url])? ([a-zA-Z1-9-.]+.[a-zA-Z1-9-]+.[a-z]{2,3} (/[a-z-/._\?=&]+)?))", "<a href=\"\1\2\" target=\"_blank\">\0</a>", $string);

$message = preg_replace("/((http(s?):\/\/)|(www.))([\S.]+)\b/i", "<a href=\"http$3://$4$5\" target=\"_blank\">$2$4$5</a>", $message);

echo "$message";

none of these work: ./test_ad.php: ?php: No such file or directory
./test_ad.php: =: command not found
./test_ad.php: line 10: syntax error near unexpected token preg_replace("' ./test_ad.php: line 10:$message = preg_replace("/((http(s?):\/\/)|(www.))([\S.]+)\b/i", "<a href=\"http$3://$4$5\" target=\"_blank\">$2$4$5</a>", $message);'
