In PHP, objects are they passed by value or by reference?
-
This is probably the most misunderstood PHP concept for people coming from other languages. A reference and a value are two completely different things. A reference is a memory address. A value can be of any type. Using the same terminology as we use for different types of pointers in C, here is how to distinguish between a reference and a value: -A ___ reference to an object is just a memory address (int). -A ___ object's value can be of any type (string, array, boolean, resource, etc.).

When I originally commented I clicked the -Notify me when new comments are added- checkbox and now every time a remark is added I get four emails with the same comment. Is there any method you may take away me from that service? Thanks!

In PHP, objects are passed by references by default. Here, reference is an alias, which allows two different variables to write to the same value. An object variable doesn't contain the object itself as value.
