foreach ($lines as $key => $val) {
    $lines[$key] = $val.$lines2[$key];
}

file_put_contents('to_write_file.txt', $lines);
?>

Because each line that you read is terminated by a newline character. So you need to strip that final character from each string in $lines, before you add the second string to it.

Use PHP: rtrim - Manual[^] :

PHP

foreach ($lines as $key => $val) {
  $temp = rtrim($val);
  $lines[$key] = $temp.$lines2[$key];
}
