php and xml--Using WDDX function (2)
Keywords: PHP, XML
XML and PHP. Chapter 1: Using WDDX function (2) (Translation: f pink rabbit oicq:1599377)
Enter WDDX
We are going to start using this WDDX (please pay attention to the related articles I translated for the content of WDDX) function through manufacturing. There is no need
to build our own XML interpreter or know the WDDX DTD, we just need to use them as we like (the translation is a bit exaggerated^_^)
WDDX functions do not require external library file support, and the execution method is usually Is generated, sequential and parallelization instructions into the WDDX package.
(The translation is a bit weird. I will improve it in the future ^_^)
WDDX, this WEB distributed data exchange, is an XML application, please see below:
" . . . is a mechanism for exchanging comprehensive data structures between application environments. It is designed to be used in conjunction with WEB applications and is a platform-neutral feature inherited from XML1.0. (defined using a DTD) and sets up a continuous parallelization component for each environment that uses WDDX. This process builds an XML request for the application data that is called continuously from this process. A continuously called WDDX XML request demonstrates an application data(?)."
(Data reference: "WDDX Document Type Definition(DTD)" http://www.wddx.org/DTD.htm—If you If you are happy
and don't hate my poor translation skills, you can wait for my WDDX article^_^)
WDDX has a simple DTD and can be used for continuous variables between different types. This DTD also recognizes character types. number. Variables of type Boolean
etc. Of course, there are arrays (only when you use numbers as indexes) and structures (when the index is a character
, it is also called an associative array). Comprehensive data structures can also be represented (e.g. arrays of arrays).
