PHP object scope [message #168330]

Can somebody explain to me the concept of object scope in PHP? I'm very new to objects in PHP and the reason I ask is because I was able to create an object within an if statement, and then access the object outside the scope of the if statement.

Example:

//only create object if some condition is met
if ($conditionTrue){
$myBook = new Book('PHP for Dummies','softcopy');
}

$myBook.read();

I would have though that this would generate an error but it didn't.

Some background to my question

I was trying to figure out how to determine which constructor to call depending on the condition that is met. The only conceivable way was to introduce an if statement but doing that, I thought would impose the issue of scope which it didn't and I'm just wondering why..
