Logical operators are based on logic based and or etc.

Example	Name	Result
$a and $b	And	`TRUE` if both `$a` and `$b` are `TRUE`.
$a or $b	Or	`TRUE` if either `$a` or `$b` is `TRUE`.
$a xor $b	Xor	`TRUE` if either `$a` or `$b` is `TRUE`, but not both.
! $a	Not	`TRUE` if $a is not TRUE.
$a && $b	And	`TRUE` if both `$a` and `$b` are `TRUE`.
$a \|\| $b	Or	`TRUE` if either `$a` or `$b` is `TRUE`.

Example as follows :

  <?php
  if(1<2 && 2<3)
  echo "Demonstration of AND ";
  
  if(2<2 || 2<3)
  echo "Demonstration of OR ";

?>
