  // this function strips out potentially dangerous info to prevent abuse of emailing
  function spam_scrubber($value){
  //create  array with potentially damaging words
    $bad_values = ['to:', 'cc:','bcc:','content-type','mime-version','multipart-mixed','content-transfer-encoding'];
  //loop through array and check for the keywords
    foreach($bad_values as $bad){
      if(stripos($value, $bad) !== false) return '';
    }
  // its important to note that this will return only once upon reaching the first keyword, it will then jump out of the loop
    return Trim($value);

  }
  //use array_map to call the scrubber function on each element in post array
  $scrubbed = array_map('spam_scrubber', $_POST);
  //use array_map to remove html js and php tags from the newly created $scrubbed array so there should be no need to sanitize data
  $stripped = array_map('strip_tags', $scrubbed);

  echo "{$stripped['name']}";

  if (isset($stripped['name']) && isset($stripped['email']) && isset($stripped['number']) && isset($stripped['email']) && isset($stripped['subject']) && isset($stripped['info'])){
    $body = "name: {$stripped['name']}\n\n Email:{$stripped['email']}\n\n number:{$stripped['bumber']}\n\n subject:{$stripped['subject']}\n\n info:{$stripped['info']}";
