Hey there, I was wondering how I could check a string broken into an array against a preg_match to see if it started with www. I already have one that check for http://www.

$stringToArray = explode(" ",$_POST['text']);

                    foreach($stringToArray as $key=>$val){
                    $urlvalid = isValidURL($val);
                    if($urlvalid){
                    $_SESSION["messages"][] = "NO URLS ALLOWED!";
                    header("Location: http://www.domain.com/post/id/".$_POST['postID']);
                    exit();
                    }
                    }

Thanks! Stefan
