I need to validate domain name from text bunch of text string to handle the following:
www.dewalist.com
dewaxxxx.com
ng.dewalist.com
dewaster.com.au
test.co.uk
...
...
I can use FILTER_VALIDATE_URL however this only validates the full url: http://www.dewalist.com bla bla which is not really what I want.
Similar like function but instead for email, it's for domain:
function extract_email_address ($string)
{
$emails = array();
$string = str_replace("\r\n",' ',$string);
$string = str_replace("\n",' ',$string);
foreach(preg_split('/ /', $string) as $token) {
$email = filter_var($token, FILTER_VALIDATE_EMAIL);
if ($email !== false) {
$emails[] = $email;
}
}
return $emails;
}
