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
