PHP: Tips of the Day
In PHP, there are two versions of logical AND and OR operators.
Operator | True if |
---|---|
$a and $b | Both $a and $b are true |
$a && $b | Both $a and $b are true |
$a or $b | Either $a or $b is true |
$a || $b | Either $a or $b is true |
Note that the && and || opererators have higher precedence than and and or. See table below:
Evaluation | Result of $e | Evaluated as |
---|---|---|
$e = false || true | True | $e = (false || true) |
$e = false or true | False | ($e = false) or true |
Because of this it's safer to use && and || instead of and and or.
