ereg question

Hi

I am trying to validate an e-mail address using this expression

[A-Za-z0-9]@[A-Za-z0-9]\.[A-Za-z0-9]

However, the escaped period is causing me a lot of grief.
Please help.

Try

function is_email( $test )
{
if ( strlen( $test ) < 7 ) return false;
return ( eregi( '^[a-z0-9._-]+@[a-z0-9._-]{2,}\.[a-z]{2,4}$', $test )
&& !ereg( '[@._-]{2}', $test ) );
}

...but does not validate umlaut-domains or top level domains like .museum
(longer than 4 chars). Latter is easily corrected if you wish to accept
those addresses.

Try this:

^[a-zA-Z0-9_\-\.]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$

No need for backslashes in char classes. If using - (dash) in char
classes, put it at 1st or last position to avoid its range meaning.
Also, + is allowed in the username part of an e-mail address (omitted in
my code too, I saw).
