Question

I am reading a database and i want to find if the field title contains only latin characters, numbers and any special character.

I know that regular expression must be used but i am not very good at reg exp.

Can anyone help.

Answer 1

This should get you started, it will match any alphanumeric characters and special characters !@#%&. and should be trivial to add any more special characters.

$field = "wtftest#$!@";

$numMatches = preg_match('/^[A-Za-z0-9!@#%$&.]+$/', $field, $matches);

if ($numMatches > 0) {
   echo "Matches";

}
