Answer 1

You'll probably be better off stripping any dot characters first:

list($tld, $tld_sub) = explode('.', trim($data, '.'));

Answer 2

you can try this one using foreach

<?php
$data = ".co.uk";
$data = explode(".", $data);
foreach($data as $value)
{
echo $value.'<br>';
}
?>

Answer 3

Use this code

<?php
$data = ".co.uk";
$list = array_filter(explode(".", $data));
$tld = $list[1];
$tld_sub = $list[2];
echo $tld;
echo "<br>";
echo $tld_sub;
?>
