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);
