");

  $replace_data_in_file = preg_replace($pattern, $replacement, $getting_file_contents);
  $writing_replaced_data = file_put_contents($file_name, $replace_data_in_file);
  echo("New file contents : " . "

");
  var_dump($replace_data_in_file);
  echo("

");

  if ($writing_replaced_data == true) {
    echo("Data in the file changed");
  }
  else {
    exit("Cannot change data in the file");
  }
}
else {
  exit("Unable to get file contents!");
}
