1.2.644. Logical Operators Favorite¶
PHP has two sets of logical operators : letters (and, or, xor) and chars (&&, ||, ^).
The analyzed code has less than 10% of one of the two sets : for consistency reasons, it is recommended to make them all the same.
Warning : the two sets of operators have different precedence levels. Using and or && is not exactly the same, especially and not only, when assigning the results to a variable. Using and or && are also the target of other analysis.
<?php
$a1 = $b and $c;
$a1 = $b and $c;
$a1 = $b and $c;
$a1 = $b or $c;
$a1 = $b OR $c;
$a1 = $b and $c;
$a1 = $b and $c;
$a1 = $b and $c;
$a1 = $b or $c;
$a1 = $b OR $c;
$a1 = $b ^ $c;
?>
