Primitive type representing a boolean value, true or
false.
Boolean values can be compared using the == and
!= operators.
Boolean values have the following logical operators:
Operation
Expression
AND
x && y
OR
x || y
NOT
!x
Rule evaluation will short-circuit on a boolean expression:
// Short-circuits at 'true' so someFunction() will never runtrue||someFunction()// Short-circuits at 'false' so someFunction() will never runfalse&&someFunction()// someFunction() will always runfalse||someFunction()
Strings can be converted into booleans using the bool()
function:
