False positive on : Same Conditions In Condition

[philippechevieux]

Hello,
I've notice that "same conditions in condition" analyzer does not take in consideration if the value is updated.

Example :

if (empty($a)) {
    $a = getValue();

    if (empty($a)) {
        $a = getValueOtherFunction();
    }
}

I guess the proper way will be to do something like this :

if (empty($a)) {
    $a = getValue();
}
if (empty($a)) {
     $a = getValueOtherFunction();
}

Am i right ?
