The following email check:

function emailCheck($intext){
     $theresults = ereg("^[^@ ]+@[^@ ]+\.[^@ \.]+$", $intext, $trashed);
if ($theresults){
    return true;
   }
}  

...may be excluding some valid email addresses...How can it be improved?

Thanks,

what I use is

function check_mail($given_email) {
$given_email = trim($given_email);
if (!eregi("^[_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3}$", $given_email)) {
$messed_up .= "email ";
}
return $messed_up;
}

the messed_up result is just part of the whole form validation

In my search for expressions, I came across this site with many expressions:

I have bookmarked it for use in future and thought you and others here might like it.

I use a cracking extension for DW MX that not just checks bad email very well but does a whole bunch of other stuffe.

BTW, it's free!

Off Topic: I loved their (yaromat's) Mac OS 8 emulator off of their home page, I once went to each computer in a lab and browsed each one to it. Should have seen the looks on student's faces when they came in. LOL

(note if you try it, I think full screen effect works only in IE on windows, if I remember right, netscape didn't fully fill the screen)
