This article mainly introduces the namespace in PHP and explains the namespace) concept, namespace being used, namespace defining, sub-namespace, calling code from namespace, etc, for more information about namespaces in PHP, see the following
1. Overview
A class file is a set of binary streams that are based on 8-bit bytes, and each data item is tightly arranged in a class file in a compact order, with no delimiters added, which makes almost all of the content stored in the entire class
The necessity of the packagePackages are used to categorize Java source files, a package in Java is a folder under Windows, the fully qualified package name is from the root directory (\SRC directory) with the dot as a delimiter, the package name

memory allocation in Java Java Program runtime memory structure is divided into: Method area, stack memory, heap memory, the local method stack several. The method area holds the loaded class data information, including: basic information: The

The bounden duty of a runtime Java Virtual machine instance is to be responsible for running a Java program. When a Java program is started, a virtual machine instance is created. When the program shuts down, the virtual machine instance also dies.
Each class byte code file is unique to a class or interface, class file in the basic information of the classes or interfaces, but not the other way, not every class or interface has a unique corresponding bytecode file, the first class or interface
For namespaces, the official documentation has been very detailed [view], and I've done some practice and summary here.
Namespace one of the most explicit purpose is to solve the problem of duplicate name, PHP does not allow two functions or

1. class file structure any class file corresponds to the definition information for the only class or interface, but in turn, the class or interface is not necessarily defined in the file (for example, a class or interface can also be generated
1. Suppose you want to reflect a class in a DLL and not reference it (that is, an unknown type):Assembly Assembly = assembly.loadfile ("Assembly path, cannot be relative path"); Loading assemblies (EXE or DLL)Object obj = assembly. CreateInstance
From PHP5.5, the keyword class can also be used for parsing class names. You can use ClassName: class to obtain a string that contains the fully qualified name of the class ClassName. This is especially useful for classes that use namespaces. {Code..
