is_integer probably wouldn't work, since you're dealing with strings here.
Your best friend here would probably be 'is_numeric' which would return true
on both the string '1' as the integer 1 true. As well as 1.1 and '1.1'. The
only one solution I could think if would be:
preg_match('/^\d+$/',
Why don't you try to check for if it is integer. You will get the function
to check the variable (is_integer not sure) in manual.
