protocol fcgi

PHP的FCGI协议的对象实现

FASTCGI是CGI的开放扩展，可为所有Internet应用程序提供高性能，而无需罚款Web服务器API。

许多现代的网络服务器，例如Nginx，Apache，Lighthttpd等，通过FCGI与PHP进行通信。因此，该协议是众所周知的，并用于许多应用程序。有关该协议的更多详细信息，请参见此处：http：//www.fastcgi.com/devkit/doc/fcgi-spec.html

用法

该库可用于实现FCGI应用程序的客户端和服务器端。例如，NGINX可以连接到PHP FCGI守护程序，或者某些库代码可以作为FCGI客户端连接到FPM。

要安装此库，只需写

$ composer require lisachenko/protocol-fcgi

之后，您可以使用API来解析/创建FCGI请求和响应。

简单的fcgi-client：

 <?php

use Lisachenko \\ Protocol \\ FCGI ;
use Lisachenko \\ Protocol \\ FCGI \\ FrameParser ;
use Lisachenko \\ Protocol \\ FCGI \\ Record ;
use Lisachenko \\ Protocol \\ FCGI \\ Record \\ BeginRequest ;
use Lisachenko \\ Protocol \\ FCGI \\ Record \\ Params ;
use Lisachenko \\ Protocol \\ FCGI \\ Record \\ Stdin ;

include \" vendor/autoload.php \" ;

// Let\'s connect to the local php-fpm daemon directly
$ phpSocket = fsockopen ( \' 127.0.0.1 \' , 9001 , $ errorNumber , $ errorString );
$ packet    = \'\' ;

// Prepare our sequence for querying PHP file
$ packet .= new BeginRequest ( FCGI :: RESPONDER );;
$ packet .= new Params ([ \' SCRIPT_FILENAME \' => \' /var/www/some_file.php \' ]);
$ packet .= new Params ();
$ packet .= new Stdin ();

fwrite ( $ phpSocket , $ packet );

$ response = \'\' ;
while ( $ partialData = fread ( $ phpSocket , 4096 )) {
    $ response .= $ partialData ;
    while (FrameParser:: hasFrame ( $ response )) {
        $ record = FrameParser:: parseFrame ( $ response );
        var_dump ( $ record );
    };
};

fclose ( $ phpSocket );

要实现FCGI服务器，只需创建一个插座并制作请求响应循环

 use Lisachenko \\ Protocol \\ FCGI ;
use Lisachenko \\ Protocol \\ FCGI \\ FrameParser ;
use Lisachenko \\ Protocol \\ FCGI \\ Record ;
use Lisachenko \\ Protocol \\ FCGI \\ Record \\ BeginRequest ;
use Lisachenko \\ Protocol \\ FCGI \\ Record \\ Params ;
use Lisachenko \\ Protocol \\ FCGI \\ Record \\ Stdin ;

include \" vendor/autoload.php \" ;

$ server = stream_socket_server ( \" tcp://127.0.0.1:9001 \" , $ errorNumber , $ errorString );

// Just take the first one request and process it
$ phpSocket = stream_socket_accept ( $ server );

$ response = \'\' ;
while ( $ partialData = fread ( $ phpSocket , 4096 )) {
    $ response .= $ partialData ;
    while (FrameParser:: hasFrame ( $ response )) {
        $ record = FrameParser:: parseFrame ( $ response );
        var_dump ( $ record );
    };
};

// We don\'t respond correctly here, it\'s a task for your application

fclose ( $ phpSocket );
fclose ( $ server );
