Automap is a fast map-based PHP autoloader.

Map-based autoloaders resolve symbols using map files. These files are created offline by a program (included) which scans your script files and extracts their symbols. At runtime, these map files are loaded by the main script and then used to resolve undefined symbols and load the corresponding PHP script files.

As a complement to the base Automap software, the optional automap PECL extension acts as an accelerator, making Automap the fastest PHP autoloader available today.
