Instead of ereg you should always use preg_match because it is faster
than ereg. Also part of your reason that it is matching any number of
digit is because what you are actually asking for is to test that there
is one or two digits in the rule...
Try the following:
if (preg_match('^[0-9]{1,2}$', $people) && preg_match('^[0-9]{1,2}$',
$rooms))
The ^ defines the start of a string and the $ defines the end of a string.
