The use of parentheses, even those not required to enforce a desired order of operations, can clarify the intent behind a piece of code. But
redundant pairs of parentheses could be misleading, and should be removed.
Noncompliant Code Example
$x = ($y / 2 + 1); // Compliant even if the parenthesis are ignored by the compiler
if ($a && (($x + $y > 0))) { // Noncompliant
//...
}
return (($x + 1)); // Noncompliant
Compliant Solution
$x = ($y / 2 + 1);
if ($a && ($x + $y > 0)) {
//...
}
return ($x + 1);
