Software modules & libraries are parts of a Program. Programs are composed of one or more independently developed modules that are not combined until the program is linked. A single module can contain one or several routines.

 

Modular programming is a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.
A module interface expresses the elements that are provided and required by the module. The elements defined in the interface are detectable by other modules. The implementation contains the working code that corresponds to the elements declared in the interface. Modular programming is closely related to structured programming and object-oriented programming, all having the same goal of facilitating construction of large software programs and systems by decomposition into smaller pieces, and all originating around the 1960s. While historically usage of these terms has been inconsistent, today "modular programming" refers to high-level decomposition of the code of an entire program into pieces, structured programming to the low-level code use of structured control flow, and object-oriented programming to the data use of objects, a kind of data structure.

 

Here is an example of a very simple authentication module. The AuthPlugin class provides a method that receives a user and password and does its magic to authenticate the user and set its permissions.

 

class AuthPlugin {

 

    private $permissions = array();

 

    function authenticate($username, $password) {

        $this->verifyUser($username, $password);

 

        $adminModules = new AdminModules();

        $this->permissions[] = $adminModules->allowRead($username);

        $this->permissions[] = $adminModules->allowWrite($username);

        $this->permissions[] = $adminModules->allowExecute($username);

    }

 

    private function verifyUser($username, $password) {

        // ... DO USER / PASS CHECKING

        // ... LOAD USER DETAILS, ETC.

    }

}

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

AuthPlugin and the AdminModule are modules used by the main application called ApplicationModule.
