Answer 1

Check your regexp variable name

$regexp = "/[one|two|three|four|five|six|seven|eight|zero]{4,}/";
$message = preg_replace($regexp, 'XXX', $message);

For number 0 to 9

preg_replace("/[^0-9]/","",$message);

Use \d if you want to remove all digits

$message  = preg_replace('/\d/', '', $message);

Or [^a-z\s] if you want to replace all except alphabets and whitespaces

$message = preg_replace('/[^a-z\s]/i', '', $message);
