The new URI is not a substitute reference for the originally requested resource. The is_int function is used to test whether the type of the specified variable is an integer or not. This is a great solution, by far the best I've seen anywhere. In this example, the pages column is a SMALLINT column. I wasn't sure about what was going on myself until I looked into the issue a bit more, but it would appear that there is an interesting caveat with the switch statement when passed a value that loosely evaluates to the Boolean false (and the integer 0 meets that condition). Note: var_dump() function is used to get structured information (type and value) about variables. Also, since there is no integer divide in PHP, we save a couple of S-L-O-W floor ()'s by doing bitshifts.
