inux环境PHP7.0安装
PHP7和HHVM比较
PHP7的在真实场景的性能确实已经和HHVM相当, 在一些场景甚至超过了HHVM。HHVM的运维复杂, 是多线程模型, 这就代表着如果一个线程导致crash了, 那么整个服务就挂了, 并且它不会自动重启。另外它采用JIT, 那么意味着, 重启以后要预热, 没有预热的情况下, 性能较为糟糕。并且多线程模型调试困难, 这对于追求稳定来说的Web服务来说, 是非常不适合的。
Nginx以及PHP7.0之前的版本可以参考此文:Linux环境Nginx安装与调试以及PHP安装
PHP7.0正式版已经在2015年11月份左右发布,目前是PHP7.0.2版本,本人最早是从2015年8月php7的第一个测试版跟起,现在正式版发布。
linux版本:64位CentOS 6.6
Nginx版本:nginx1.8.0
php版本:php-7.0.2

如果配置错误,需要安装需要的模块,直接yum一并安装依赖库
# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel MySQL pcre-devel
# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
# /etc/init.d/php-fpm
- <?php
- //time /usr/local/php5/bin/php search_by_key.php
- $a = array();
- for($i=0;$i<600000;$i++){
- $a[$i] = $i;
- }
- foreach($a as $i)
- {
- array_key_exists($i, $a);
- }
- ?>
生成一个 60 万元素的数组,通过查找key 的方式,来确定key是否存在。

官网地址:http://php.net/opcache
使用下列推荐设置来获得较好的 性能:
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1
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
