patterns in Regular Expression

[Anon]

hi,

if the user types a www adress in a textarea - on the output should the the text be an active link. the pattern in preg_match should look for www and store the rest of the urlname.

something here is wrong...

would be apprecheated for some help.

(preg_match ("/www.(^$)*/i", mysql_result($result, $i, "Text"), $match)) {
print ereg_replace($match[0], "<a href=http://".$match[0].">".$match[0]."</a>", mysql_result($result, $i, "Text"))

if you would like to store anything after "www.", you should use following regexp
<?
$url="www.something.com";
ereg("www.(.*)$",$url,$args);

arg[1] will give you 'something.com'

?>

some explanations on your 'regex' "/www.(^$)*/"

"www" string must begin with "www"
"." any character, if you want "dot", you have to use "."
(^$) wrong. ^ means from begin a string, $ to end - you're missing the range.
"*" any characters
