Validating Email Addresses

[Anon]

Is it possible to validate that an email address submitted through a form is in fact an actual email address?

Hi
If you want to just check that the input follows a regular format like '[e-mail]' you could use a function like this:

function email_check ($intext) {
$email= ereg("^[@ ]+@[^@ ]+.[^@ . +$",$intext);
if ($email) {
return TRUE;
} else {
return FALSE;
}
}

Try this to validate whether an email address field value exists and has accurate syntax:

// set an error flag to 0...
$err = 0;

// for email field name "Email"

if (!$Email) {
$em=0;
$err=1;
} elseif (!eregi("^{[_.0-9a-z-]+@([0-9a-z][0-9a-z-]+.)+[a-z]{2,3}$",} $Email)) {
$em=0;
$err=1;
} else {
$em=1;
}

if ($em == 0) {
echo "bad syntax";
} else {
echo "syntax OK";
}
