Converting URL's to hyperlinks

[Phoenix_Down]

I made this little function, but it's not working correctly (or at all). When I post to my guestbook and go to view it afterwards, the entry message is blank.

function url2hl($hl) {

$hl = preg_replace("[b](.*?)[/b]://[b](.*?)[/b]", "<a href=\"[b]\\1[/b]://[b]\\2[/b]\" target=\"_blank\">[b]\\1[/b]://[b]\\2[/b]</a>", $hl);

return $hl;

}

I'm pretty new at these 'replace' functions, so any help will be greatly appreciated. 🙂

much simpler way to make url-s...

function urlMaker($text, $wrap)
{
$text = str_replace("\n", " \n ", $text);

$words=explode(' ',$text);
for($i=0;$i<sizeof($words);$i++)
{
if (strlen($words[$i])>$wrap) $word=chunk_split($words[$i],$wrap,' ');
else $word=$words[$i];

$c=0;

if(strtolower(substr($words[$i],0,7))=='http://'){$c=1;$word='<a href="'.$words[$i].'" target="_new">'.$word.'</a>';}
elseif(strtolower(substr($words[$i],0,8))=='https://') {$c=1;$word='<a href="'.$words[$i].'" target="_new">'.$word.'</a>';}
elseif(strtolower(substr($words[$i],0,6))=='ftp://') {$c=1;$word='<a href="'.$words[$i].'" target="_new">'.$word.'</a>';}
elseif(strtolower(substr($words[$i],0,4))=='ftp.') {$c=1;$word='<a href="ftp://'.$words[$i].'" target="_new">'.$word.'</a>';}
elseif(strtolower(substr($words[$i],0,4))=='www.') {$c=1;$word='<a href="http://'.$words[$i].'" target="_new">'.$word.'</a>';}
elseif(strtolower(substr($words[$i],0,7))=='mailto:') {$c=1;$word='<a href="'.$words[$i].'">'.$word.'</a>';}
elseif(strpos($words[$i],'@')>1 && strpos($words[$i], '.')> 4){$c=1;$word='<a href="mailto:'.$words[$i].'" target="_new">'.$words[$i].'</a>';}

if ($c==1) $words[$i]=$word;
}

$ret = str_replace (" \n ", "\n", implode(' ',$words));
return $ret;
}
?>

Thanks. I modified it a bit:

function url2hl($text, $wrap) {

$text = str_replace("\n", " \n ", $text);

$words=explode(' ',$text);
for($i=0;$i<sizeof($words);$i++)
{
if (strlen($words[$i])>$wrap) $word=chunk_split($words[$i],$wrap,' ');
else $word=$words[$i];

$c=0;

if(strtolower(substr($words[$i],0,7))=='http://'){$c=1;$word='<a href="'.$words[$i].'" target="_blank">'.$words[$i].'</a>';}
 elseif(strtolower(substr($words[$i],0,8))=='https://') {$c=1;$word='<a href="'.$words[$i].'" target="_blank">'.$words[$i].'</a>';}
elseif(strtolower(substr($words[$i],0,6))=='ftp://') {$c=1;$word='<a href="'.$words[$i].'" target="_blank">'.$words[$i].'</a>';}
elseif(strtolower(substr($words[$i],0,4))=='ftp.') {$c=1;$word='<a href="ftp://'.$words[$i].'" target="_blank">'.$words[$i].'</a>';}
elseif(strtolower(substr($words[$i],0,4))=='www.') {$c=1;$word='<a href="http://'.$words[$i].'" target="_blank">'.$words[$i].'</a>';}
 elseif(strtolower(substr($words[$i],0,7))=='mailto:') {$c=1;$word='<a href="'.$words[$i].'" target=\"_blank\">'.$words[$i].'</a>';}
elseif(strpos($words[$i],'@')>1 && strpos($words[$i], '.')> 4){$c=1;$word='<a href="mailto:'.$words[$i].'" target="_blank">'.$words[$i].'</a>';}

if ($c==1) $words[$i]=$word;
}

$ret = str_replace (" \n ", "\n", implode(' ',$words));
return $ret;

}

How do I turn the <a href="address" target="_blank">address</a> back to hyperlink?
