Defining multiple namespaces in the same fileMultiple namespaces may also be declared in the same file. There are two allowed syntaxes.
Example #1 Declaring multiple namespaces, simple combination syntax
This syntax is not recommended for combining namespaces into a single file. Instead it is recommended to use the alternate bracketed syntax.
Example #2 Declaring multiple namespaces, bracketed syntax
It is strongly discouraged as a coding practice to combine multiple namespaces into the same file. The primary use case is to combine multiple PHP scripts into the same file. To combine global non-namespaced code with namespaced code, only bracketed syntax is supported. Global code should be encased in a namespace statement with no namespace name as in: Example #3 Declaring multiple namespaces and unnamespaced code
No PHP code may exist outside of the namespace brackets except for an opening declare statement. Example #4 Declaring multiple namespaces and unnamespaced code
