regular expression

Hi,

being not very good at php regular expression, could anyone help me giving
the regular expression for :
- an e-mail address,
- a website address (including sub-domain if possible).

many thanks in advance,

These are primitive, but have worked for me:
// replace URLs that aren't in an anchor tag
$pattern='/(http:\/\/[^\s\"\)<>]+)/i';

// get email addresses to link
$pattern='/([a-z][a-z0-9_.-\/]*@[^\s\"\)\?<>]+)/i';

These are patterns that are used with the preg_* functions

While thinking about how cool George Washington was, nyso blurted:

being not very good at php regular expression, could anyone help me giving
the regular expression for :
- an e-mail address,


here's a cool function for checking if an email address is valid:
(please pardon the ridiculous linewrapping)

function is_email($email) {

return(preg_match("/^[-_.[:alnum:]]+@((([[:alnum:]]|[[:alnum:]][[:alnum:]-]*[[:alnum:]])\.)+(ad|ae|aero|af|ag|ai|al|am|an|ao|aq|ar|arpa|a s|at|au|aw|az|ba|bb|bd|be|bf|bg|bh|bi|biz|bj|bm|bn |bo|br|bs|bt|bv|bw|by|bz|ca|cc|cd|cf|cg|ch|ci|ck|c l|cm|cn|co|com|coop|cr|cs|cu|cv|cx|cy|cz|de|dj|dk| dm|do|dz|ec|edu|ee|eg|eh|er|es|et|eu|fi|fj|fk|fm|f o|fr|ga|gb|gd|ge|gf|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs |gt|gu|gw|gy|hk|hm|hn|hr|ht|hu|id|ie|il|in|info|in t|io|iq|ir|is|it|jm|jo|jp|ke|kg|kh|ki|km|kn|kp|kr| kw|ky|kz|la|lb|lc|li|

email));

Why? It'd be unthinkably messy.

No, it seems easy to regex users.
E-mail is ok but url seems more difficult.

for the url regex, I tested it and it matches a simple "test" string as the
minimum should be "test.somthing".
any idea ?
