Yes, you squashed all the bugs!

One more piece of advice here: check out Yoda Conditions. These are an alternate style that can help avoid forgetting to use the == instead of = in the if statements.

The main idea is to reverse the order of the items in your if statement - i.e. instead of doing:

if ($variable == 'constant') {
    // do something
}

Move the constant (i.e. the non-variable) in the beginning of conditional clause:

if ('constant' == $variable) {
    // do something
}

Why might this be better? Well, it's the same really. But if you accidentally use a single =, PHP will throw a syntax error that's easy to debug. That would have made this challenge much easier to debug!
