The preceding mysql. php is an encapsulated mysql database function in singleton mode. Therefore, the object is taken as a static mysql: getObject ();
The code is simple.
The parameter of the openUri ('') method can be a file, so xml data is written to this file.
Or php: // output to the buffer, and then flush to the page
