Bug Best Practice introduced by
The expression $maxAge of type integer|false is loosely compared to false; this is ambiguous if the integer can be zero. You might want to explicitly use === null instead.

In PHP, under loose comparison (like ==, or !=, or switch conditions), values of different types might be equal.

For integer values, zero is a special case, in particular the following results might be unexpected:

0   == false // true
0   == null  // true
123 == false // false
123 == null  // false

// It is often better to use strict comparison
0 === false // false
0 === null  // false
