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.
function isValidURL($url)
{
return preg_match('|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i', $url);
}
$stringToArray = explode(" ",$_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
You want something like:
%^((https?://)|(www\.))([a-z0-9-].?)+(:[0-9]+)?(/.*)?$%i
this is using the | to match either http://
or www
at the beginning. I changed the delimiter to %
to avoid clashing with the |
