nginx-php类似nginx-lua的扩展，nginx-php中文开发文档

2020年6月2日10:19:03

github：https://github.com/rryqszq4/ngx_php7

php5的版本 https://github.com/rryqszq4/ngx_php

发现是从框架性能测试的 https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=fortune发现的

这个是参照ngx_lua做的，目前我自己还未做测试，先把文档翻译成中文的，作者也应该是中国人，官方QQ群：558795330

感谢ta 对发展php的生态做的贡献

因为cnblog的目前不支持mkdown语法，在有道上分享的一个更方便观看的版本

ngx_php7

ngx_php7是高性能Web服务器nginx的扩展模块，它实现嵌入式php7脚本来处理nginx的位置和变量。

ngx_php7借鉴ngx_lua的设计，并致力于提供比php-cgi，mod_php，php-fpm,和hhvm具有显着性能优势的非阻塞Web服务。

ngx_php7不想替换任何东西，只想提供一个解决方案。

有ngx_php5的旧版，它记录了我过去的一些代码实践，也很有价值。

ngx_php7 and php 的性能测试

目录

• 官方php有什么不同
• 运行条件
• 安装
• 概要
• 测试
• 指令
• Nginx API for php
• Nginx non-blocking API for php
• Nginx 常量
• 版权和许可

官方php有什么不同

• 全局变量在每个请求中都不安全
• 类的静态变量在每个请求中都不安全
• 不要设计单例模式
• 本机IO功能可以正常工作，但是会减慢Nginx的速度

运行条件

• 仅支持 Linux
• PHP-7.0.* ~ PHP-7.4.*
• nginx-1.4.7 ~ nginx-1.17.8

安装

编译安装

 

 

$ wget 'http://php.net/distributions/php-7.3.10.tar.gz'
$ tar xf php-7.3.10.tar.gz
$ cd php-7.3.10

$ ./configure --prefix=/path/to/php --enable-embed
$ make && make install

$ git clone https://github.com/rryqszq4/ngx_php7.git

$ wget 'http://nginx.org/download/nginx-1.12.2.tar.gz'
$ tar -zxvf nginx-1.12.2.tar.gz
$ cd nginx-1.12.2

$ export PHP_CONFIG=/path/to/php/bin/php-config
$ export PHP_BIN=/path/to/php/bin

$             --add-module=/path/to/ngx_php7
$ make && make install

CentOS / RedHat 7

 

yum -y install https://extras.getpagespeed.com/release-el7-latest.rpm
yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm yum-utils
yum-config-manager --enable remi-php73
yum install nginx-module-php7

编辑 nginx.conf 并在顶部加载所需的模块：

load_module modules/ndk_http_module.so;
load_module modules/ngx_http_php_module.so;

Docker

 

$ docker build -t nginx-php7 .
$ : "app.conf: Create nginx config"
$ docker run -p 80:80 -v $PWD/app.conf:/etc/nginx/conf.d/default.conf nginx-php7

• port: int

context: rewrite_by_php*, access_by_php*, content_by_php*

使用套接字资源套接字启动到地址的连接，该套接字必须是有效的
使用ngx_socket_create()创建的套接字资源。

ngx_socket_close

syntax: ( yield ngx_socket_close(resource $socket) ) : bool

parameters:

• socket: resource

context: rewrite_by_php*, access_by_php*, content_by_php*

ngx_socket_close（）关闭套接字给定的套接字资源。 此功能特定于
套接字，不能在任何其他类型的资源上使用。

ngx_socket_send

syntax: ( yield ngx_socket_send(resource $socket, string $buf, int $len) ) : int

parameters:

• socket: resource
• buf: string
• len: int

context: rewrite_by_php*, access_by_php*, content_by_php*

函数ngx_socket_send（）将len个字节从buf发送到套接字套接字。

syntax: ( yield ngx_socket_recv(resource $socket, string &$buf, int $len) ) : int

parameters:

• socket: resource
• buf: string
• len: int

context: rewrite_by_php*, access_by_php*, content_by_php*

ngx_socket_recv（）函数从套接字接收buf中的len字节数据。 ngx_socket_recv（）可以是
用于从连接的套接字收集数据。

buf通过引用传递，因此必须在参数列表中将其指定为变量。
ngx_socket_recv（）从套接字读取的数据将以buf返回。

ngx_socket_recvpage

syntax: ( yield ngx_socket_recvpage(resource $socket, string &$buf, int &$rc) ) : int

parameters:

• socket: resource
• buf: string
• rc: int

context: rewrite_by_php*, access_by_php*, content_by_php*

syntax: ngx_socket_recvsync(resource $socket, string &$buf, int $len) : int

parameters:

• socket: resource
• buf: string
• len: int

context: rewrite_by_php*, access_by_php*, content_by_php*

ngx_socket_clear

syntax: ngx_socket_recv(resource $socket) : bool

parameters:

• socket: resource

context: rewrite_by_php*, access_by_php*, content_by_php*

Close the socket resource and is blocking but hight performance.

ngx_php7

ngx_php7是高性能Web服务器nginx的扩展模块，它实现嵌入式php7脚本来处理nginx的位置和变量。

ngx_php7借鉴ngx_lua的设计，并致力于提供比php-cgi，mod_php，php-fpm,和hhvm具有显着性能优势的非阻塞Web服务。

ngx_php7不想替换任何东西，只想提供一个解决方案。

有ngx_php5的旧版，它记录了我过去的一些代码实践，也很有价值。

官方php有什么不同

• 全局变量在每个请求中都不安全
• 类的静态变量在每个请求中都不安全
• 不要设计单例模式
• 本机IO功能可以正常工作，但是会减慢Nginx的速度

运行条件

• 仅支持 Linux
• PHP-7.0.* ~ PHP-7.4.*
• nginx-1.4.7 ~ nginx-1.17.8
