What is a single case?
A singleton requires that a class has and only one instance, providing a global access point. So it has to bypass the regular controller so that it can only have one instance for the user to use, while using a few instances of not caring, so this is the designer's responsibility
Copy Code code as follows:
In JavaScript, singletons serve as a shared resource namespace which isolate code from the global implementation So as to provide a single point of access
have a complete separation between the actual action name and the URL format that needs to be invoked. This allows custom formatting of the URL to be customized as if he were part of the response. We are no longer restricted to the structure of the file or to the parameters of the request, and the URL of an action looks like the parsing we want. For example, an index action call to a article module is usually as follows:Http://localhost/myapp_dev.php

A singleton pattern ensures that a class has only one instance, and instantiates it and provides this instance to the entire system globally. Instead of creating an instance copy, it returns a reference to an instance stored within a singleton class.
2. Solve the problem/use scenario
In the case of database applications, a single example pattern can be used to avoid the resources consumed by a large number of new operations.If you need a cla
PHP file read operations involve more PHP file manipulation functions than file writes, which are described in detail in code instances.
The way in which data is stored in a text file is mainly three steps and some file operation functions are as follows:
1, open the file (file operation function: fopen)2, file data read (File operation function: fgets, file, ReadFile, feof, etc.)3, close the file (file operation function: fclose)
The following is still a PHP file read and write operation cod
