Hi,

in preg_match you can define any pattern for matching the user input.

And then use the preg_match method find the number of matches in it.

<?
$pattern = "";// Write regular expression here
$string = ""; //Variable to hold user input
//use preg_match to find no of matched
$count = preg_match($pattern, $string); 
print $count; //based on the count value you can validate the input
?>

Thanks
