PHP Logical Operators

PHP provides three logical operators when we test more than one condition to make decisions. These are: && (meaning logical AND), || (meaning logical OR) and ! (meaning logical NOT).

&&And operator performs logical conjunction on two expressions
(if both expressions evaluate to True, result is True. If either expression evaluates to False, the result is False)
||Or operator performs a logical disjunction on two expressions
(if either or both expressions evaluate to True, the result is True).
!Not operator performs logical negation on an expression.
