Definition - What does Overloading mean? Overloading refers to the ability to use a single identifier to define multiple methods of a class that differ in their input and output parameters. Overloaded methods are generally used when they conceptually execute the same task but with a slightly different set of parameters.
The Unix shell may be said to consist almost entirely of an autoloader (program), as its main job is to search a path of directories to load and execute command files. In PHP 5, autoload functionality is triggered when referencing an undefined class. One or more autoload functionsâimplemented as the __autoload magic function or any function registered to the SPL autoload stackâis called and given the opportunity to define the class, usually by loading the file it is defined in.
