Description

From manual page: https://php.net/function.filter-var


There is no example with if and I saw a lot of implementations like:

if (!filter_var($value, $type)) {
    echo 'error';
}

and it should be:

if (filter_var($value, $type) !== $value) {
    echo 'error';
}

Especially, when you validated with FILTER_VALIDATE_BOOLEAN filter.
