 Gotcha, that's clear.

 I decided to read the PHP documentation:

 http://www.php.net/manual/en/language.types.integer.php#language.types.integer.casting

 "Converting to integer

 To explicitly convert a value to integer, use either the (int) or
 (integer) casts. However, in most cases the cast is not needed, since a
 value will be automatically converted if an operator, function or control
 structure requires an integer argument. A value can also be converted to
 integer with the intval() function.

 See also: type-juggling.
 From booleans

 FALSE will yield 0 (zero), and TRUE will yield 1 (one)."
