PHP Namespaces

Namespaces are qualifiers that solve two different problems:

  1. They allow for better organization by grouping classes that work together to perform a task
  2. They allow the same name to be used for more than one class

The “diamond problem” (sometimes referred to as the “deadly diamond of death”) is an ambiguity that arises when two classes B and C inherit from A, and class D inherits from both B and C
