 explode() is string function and returns array of strings. Therefore, 
 type is integer.


Oops. Obviously this line is wrong. It should be

There for type is STRING not integer...

explode() is string function and returns array of strings. 
Therefore, type is integer.

   if (is_int($section)) {
 echo section: $sectionbr\n;
   } else {
 echo Invalid section (NON_INT: $section)br\n;
   }
 
 Um, why does it fail when I hit the script with any INT?


'1' is not integer, but string.
1 is integer.

BTW, all user inputs(POST/GET/etc) are string.
