Answer 1

Use an associative array to remember which domains you've already processed, and skip to the next line when you get a duplicate.

$domains_seen = array();
foreach($lineFromText as $line){
  $words = explode(";",$line);
  $domain = $words[5];
  if array_key_exists($domain, $domains_seen) {
    continue;
  }
  $domains_seen[$domain] = true;
  ...
}
