func Test_exec(t *testing.T) { engine.Initialize() ctx := &engine.Context{ Output: os.Stdout, } err := engine.RequestStartup(ctx) if err != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) err = ctx. Exec ( "/tmp/index.php" ) if err != nil { fmt.Println(err) } } |
其中 /tmp/index.php 的内容为

<?php echo ( "hello\n" ); |

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

Eval ( "return $greeting;" ) if err != nil { fmt.Println(err) } defer engine.DestroyValue(val) if engine.ToString(val) != "hello" { t.FailNow() } } |
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。

func Test_log(t *testing.T) { engine.PHP_INI_PATH_OVERRIDE = "/tmp/php.ini" engine.Initialize() ctx := &engine.Context{ Log: os.Stderr, } err := engine.RequestStartup(ctx) if err != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) _, err = ctx. Eval ( "error_log('hello', 4); trigger_error('sent from golang', E_USER_ERROR);" ) if err != nil { fmt.Println(err) } } |
其中 /tmp/php.ini 的内容为
1
2
|
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

$_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

Eval ( "ob_start(); echo ('hello');" ) if buffer.String() != "" { t.FailNow() } ctx. Eval ( "fastcgi_finish_request();" ) if buffer.String() != "hello" { t.FailNow() } } |
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。
