为了给自己开发一个支持 fastcgi 的 http server 做准备。剥离了 nanoweb 的 fastcgi 接口部分代码。测试了下。 成功了

<?php
    define("FCGI_VERSION_1", 1);
    define("FCGI_BEGIN_REQUEST", 1);
    define("FCGI_ABORT_REQUEST", 2);
    define("FCGI_END_REQUEST", 3);

		$ret["length"]=(ord($data{4}) << 8)+ord($data{5});
		$ret["content"]=substr($data, 8, $ret["length"]);
		return($ret);
	
	}
?>

关键在于

$nsv["SCRIPT_FILENAME"]='/tmp/info.php';

这个脚本环境变量的 发送。。 否则 php-cgi 会现实

我想问下 在传送 FCGIParams 时，你是把全部参数 连接成一个字符串 然后包装成一个 FCGIParams发送过去的 
每次build_fcgi_nvpair的时候 返回参数都是 $nvpair . $name . $value; 
我想问下$nvpair这个参数连接起来的用处是啥呢？
