==== Noncompliant code example

[source,php]
----
function getResult() {
    $result = 42;
    if (shouldBeZero()) {
        $result == 0; // Noncompliant: no side effect, was an assignment intended?
    }
    return $result;
}
----

==== Compliant solution

[source,php]
----
function getResult() {
    $result = 42;
    if (shouldBeZero()) {
        $result = 0; // Compliant
    }
    return $result;
}
