will be helpful for those in need Further to my comment, here is what I meant by passing the variables as an array then looping over them, applying your patterns, and passing $errors by reference:
$patterns = array(
"fname" => '/^[a-zA-Z]{2,15}$/',
"lname" => '/^[a-zA-Z]{2,15}$/',
"phone" => '/^(\(\d{3}\))(\d{3}\-)(\d{4})$/',
"city" => '/^[a-zA-Z]{3,20}$/',
"state" => '/^[a-zA-Z]{2}$/',
);
$errors = array(
"fname" => "Please enter your FIRST name between 2 and 15 letters.<br>",
"lname" => "Please enter your LAST name between 2 and 15 letters.<br>",
"phone" => "Please enter your phone number in (###)###-### format.<br>",
"city" => "Please enter your city name between 3 and 20 letters.<br>",
"state" => "Please enter your state's abbreviation (Example: CA).<br>",
);
// Pass by ref--------------------------------vv

{
$new = false;
foreach($input as $key => $value) {
if(preg_match($patterns[$key], $value, $match))
unset($errors[$key]);

return (empty($errors));

$valid = false;

$inputs = $_POST;
