As I understand it, the characters that make up an Internet domain name can
consist of only alpha-numeric characters and a hyphen
(http://tools.ietf.org/html/rfc3696)

So I'm trying to write regex that will provide a basic url format validation:

starts with http or https (the only 2 prots I'm interested in), is followed by
'://', then ([any alpha-numeric or hyphen] followed by a '.' appearing 1 or more
times), then followed by anything *, and is case-insensitive.

I tried this:

if (preg_match('/^(http|https):\/\/([a-z0-9-]\.+)*/i', $urlString))
{
$valid == true;
}
else
{
$valid == false;
}

but no luck.

Any suggestions welcome...

Thanks in advance.
