File cache class

File cache class is a PHP Class that can cache arbitrary data in files in order to reduce the time necessary to regenerate pages or other types of data that do not change every time they are requested. It features safe locking of cache files to avoid data corruption caused by simultaneous accesses during cache file updates, portable locking schemes, and the ability to set a cache expiry date or timeout period. Cache files can store user-defined headers besides the cached data, and also standard headers used in HTTP like content-length:, date:, expires:, etag:, etc. It has been tested under Linux, SunOS and Windows.

Recent releases

  •  30 Apr 2009 09:42

    Release Notes: This release fixes a bug that was preventing the class from checking cache file integrity.

    •  04 Feb 2008 12:41

      Release Notes: This release fixes a bug that was preventing the reading of cache file headers longer than the default file buffering length limit.

      •  29 Apr 2004 07:10

        Release Notes: An issue with not reinitializing the headers of an outdated cache file that was making file cache refreshing fail when setting headers that were already defined in the outdated cache file were fixed. Explicit non-blocking file locking methods are now used in the updating method.

        •  21 Nov 2003 11:24

          Release Notes: This release implements a function, "updating", that determines if the cache is currently locked for update by a concurrent process, or if the cache is available for reading or updating. A simple example of usage of the class is also provided.

          •  28 Mar 2003 03:05

            Release Notes: This release can cache headers which contain special values to be used to generate the cache. These values are verified to determine if the cache is up-to-date. Several bugs have been fixed.
