Php dba cache

1,656 views

Published on

The php-dba-cache uses the database (dbm-style) abstraction layer to cache/store
your PHP objects, strings, integers or arrays. Even instances of SimpleXMLElement
can be put to the cache. You dont have to matter about the size of the cache-file.
It depends on the free space of your disk.
