OCP - Opcache Control Panel   (aka Zend Optimizer+ Control Panel for PHP)

Author: _ck_   (with contributions by GK, stasilok)

Version: 0.1.6

Free for any kind of use or modification, I am not responsible for anything, please share your improvements

 

* revision history

0.1.6  2013-04-12  moved meta to footer so graphs can be higher and reduce clutter

0.1.5  2013-04-12  added graphs to visualize cache state, please report any browser/style bugs

0.1.4  2013-04-09  added "recheck" to update files when using large revalidate_freq (or validate_timestamps=Off)

0.1.3  2013-03-30  show host and php version, can bookmark with hashtag ie. #statistics - needs new layout asap

0.1.2  2013-03-25  show optimization levels, number formatting, support for start_time in 7.0.2

0.1.1  2013-03-18  today Zend completely renamed Optimizer+ to OPcache, adjusted OCP to keep working

0.1.0  2013-03-17  added group/sort indicators, replaced "accelerator_" functions with "opcache_"

0.0.6  2013-03-16  transition support as Zend renames product and functions for PHP 5.5 (stasilok)

0.0.5  2013-03-10  added refresh button (GK)

0.0.4  2013-02-18  added file grouping and sorting (click on headers) - code needs cleanup but gets the job done

0.0.2  2013-02-14  first public release

 

* known problems/limitations:

Unlike APC, the Zend OPcache API

 - cannot determine when a file was put into the cache

 - cannot change settings on the fly

 - cannot protect opcache functions by restricting execution to only specific scripts/paths

 

* todo:

Extract variables for prefered ordering and better layout instead of just dumping into tables

File list filter
