<!-- Logical Operators in PHP -->
<!-- Operators
    1. && -> Logical AND -> (4<2)&&(4>3)- output False
        2. || -> Logical OR -> (4<2)||(4>3)- output True
     3. ! -> Logical Not -> !(4<2) -> output  True
        4. and -> Logical AND -> (4<2)and(4>3)- output False
      5. or -> Logical OR -> (4<2)or(4>3)- output True
        xor -> Exclusive OR ->(4<2)xor(4>3)- output True
