-This is an extension that aims to implement some efficient data access
-interfaces and classes. You'll find the classes documented using php
-code in the file spl.php or in the corresponding .inc file in the examples
-subdirectory. Based on the internal implementations or the files in the
-examples subdirectory there are also some .php files to experiment with.
-
-The .inc files are not included automatically because the are sooner or
-later integrated into the extension. That means that you either need to
-put the code of examples/autoload into your autoprepend file or that you
-have to point your ini setting auto_prepend_file to this file.
