返回的value的生命周期所有权是golang程序,所以我们要负责DestroyValue
设置全局变量来传参

传递进去的参数的生命周期是php控制的,在request shutdown的时候内存会被释放。

其中 /tmp/php.ini 的内容为

|
error_reporting = E_ALL
error_log = "/tmp/php-error.log"
|
错误会被输出到 /tmp/php-error.log。直接调用error_log会同时再输出一份到stderr

所有的PHP超级全局变量都会被初始化为传递进去的Request的值,包括
1
2
3
4
5
6
|
$_SERVER
$_GET
$_POST
$_FILE
$_COOKIE
$_ENV
|
echo的内容,http code和http header会被写回到传入的ResponseWriter
fastcgi_finish_request
PHP-FPM 很常用的一个功能是 fastcgi_finish_request ,用于在php里做一些异步完成的事情。这个特殊的全局函数必须支持

实际的作用就是把output提前输出到 ResposneWriter 里去,让调用方知道结果。对于当前进程的执行其实是没有影响的,只是影响了output。
