PHP preg_match for only numbers and letters, no special characters

Question

I don\'t want preg_match_all ... because the form field only allows for numbers and letters... just wondering what the right syntax is...

Nothing fancy ... just need to

Answer 1

If you want to match more than 1, then you'll need to, however, provide us with some code and we can help better.

although, in the meantime:

preg_match("/([a-zA-Z0-9])/", $formContent, $result);
print_r($result);
