1.2.966. Parenthesis As Parameter¶

Using parenthesis around parameters used to silent some internal check. This is not the case anymore in PHP 7, and should be fixed by removing the parenthesis and making the value a real reference.

<?php
// example extracted from the PHP manual
function getArray() {
    return [1, 2, 3];
}

function squareArray(array &$a) {
    foreach ($a as &$v) {
        $v \*\*\= 2;
    }
}

// Generates a warning in PHP 7.
squareArray((getArray()));
?>
