PHP7's performance in real scenarios is indeed comparable to HHVM, and even exceeds HHVM in some scenarios. The operation and maintenance of HHVM is complex and it is a multi-threaded model. This means that if a thread causes a crash, the entire service will hang and it will not automatically restart. In addition, it uses JIT, which means that it needs to be warmed up after restarting. Without preheating, the performance will be worse. Moreover, the multi-threaded model is difficult to debug, which is very unsuitable for web services that pursue stability.
For versions before Nginx and PHP7.0, please refer to this article: Linux environment Nginx installation and debugging and PHP installation
The official version of PHP7.0 has been released around November 2015, and is currently PHP7.0.2 version, I first started following the first beta version of php7 in August 2015, and now the official version is released.
linux version: 64-bit CentOS 6.6
Nginx version: nginx1.8.0
php version: php-7.0.2
Download

你也可以禁用 opcache.save_comments 并且启用 opcache.enable_file_override。 需要提醒的是，在生产环境中使用上述配置之前，必须经过严格测试。 因为上述配置存在一个已知问题，它会引发一些框架和应用的异常， 尤其是在存在文档使用了备注注解的时候。

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
