Questions tagged [autoload]

autoload is a language convention which allows missing classes or method dependencies to be loaded on-demand.

autoload is implemented differently among languages which include it:

  • Perl's AUTOLOAD allows you to dynamically interpret method calls.
  • PHP's __autoload loads classes. To handle missing methods, the __call() magic method may be used.
  • Ruby's autoload command loads modules.

Creating object from variable using Namespaces and Autoload in PHP
