regular expression

[nyso]

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

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

function is_email($email ) {

return(preg_mat ch("/^[-_.[:alnum:]]+@((([[:alnum:]]|[[:alnum:]][[:alnum:]-]*[[:alnum:]])\.)+(ad|ae|aer o|af|ag|ai|al|a m|an|ao|aq|ar|a rpa|as|at|au|aw |az|ba|bb|bd|be |bf|bg|bh|bi|bi z|bj|bm|bn|bo|b r|bs|bt|bv|bw|b y|bz|ca|cc|cd|c f|cg|ch|ci|ck|c l|cm|cn|co|com| coop|cr|cs|cu|c v|cx|cy|cz|de|d j|dk|dm|do|dz|e c|edu|ee|eg|eh| er|es|et|eu|fi| fj|fk|fm|fo|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|in fo|int|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 ?
