ToInt filter doesn't transform NULL to 0

[tasmaniski]

Using zend input filter I find a bug in a case when I don't send data key to the filter,
but still want to transform/filter data value. So, it should be filtered from NULL to 0

I suppose this part of the code should skip: array, object and resource

// is_scalar() does not consider NULL to be scalar
if (! is_scalar($value)) {
    return $value;
}

But unfortunately it skiped NULL value also.

So, it should be filtered from NULL to 0

Sorry, this is wrong, because:

• 0 is concrete value
• null represents no value

So it works like described:

Zend\Filter\ToInt allows you to transform a scalar value into an integer.
