PHP7和HHVM比較
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, 这就代表着假设一个线程导致crash了, 那么整个服务就挂了, 而且它不会自己主动重新启动。
另外它採用JIT, 那么意味着, 重新启动以后要预热, 没有预热的情况下, 性能较为糟糕。而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之前的版本号能够參考此文：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月份左右公布。眼下是PHP7.0.2版本号，本人最早是从2015年8月php7的第一个測试版跟起，如今正式版公布。
linux版本号：64位CentOS 6.6
Nginx版本号：nginx1.8.0
php版本号：php-7.0.2

假设配置错误，须要安装须要的模块，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

$a = array();
for($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
你也能够禁用 opcache.save_comments 而且启用 opcache.enable_file_override。
须要提醒的是，在生产环境中使用上述配置之前。必须经过严格測试。 由于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。
