PHP && Logic and operator usage instructions

The following foo () is not called because they are "shorted" by the operator.

$a = (false && foo ());

$b = (true | | foo ());

$c = (False and foo ());

$d = (true or foo ());

"| |" has a higher priority than "or"

$e = False | | True $e is assigned a value of (false | | true), and the result is true

$f = False or true; $f is assigned false [Altair NOTE: ' = ' has a higher precedence than ' or ']

Var_dump ($e, $f);

"&&" has a higher priority than "and"

$g = True && false; $g is assigned (true && false) and the result is false

$h = True and false; $h is assigned true [Altair Note: ' = ' has a higher precedence than ' and ']

Var_dump ($g, $h);

?>

The use of the operator is a feature that can be reduced by using the IF
