PHP利用fscckopen实现异步处理方法教程

用fscckopen实现异步调用php , 这样客户端请求时就可以秒开，无阻塞，把一些耗时的任务放在后台运行。具体请参考原文：使用fscok实现异步调用PHP

文件test.php

我简化成只用GET方法。方便理解。并且调用同一页面，逻辑上调用其它页面可能会更好一点。不过测试没发现问题。

<?php
ignore_user_abort(TRUE); //如果客户端断开连接，不会引起脚本abort.
set_time_limit(0);//取消脚本执行延时上限
if($_GET){
sleep(10);
writelog("get=" . $_GET['get']); //10秒后创建log.txt
exit;
$url="http://127.0.0.1/test.php?get=1";
triggerRequest($url);
echo "success";
function triggerRequest($url){
$method = "GET"; //可以通过POST或者GET传递一些参数给要触发的脚本
$url_array = parse_url($url); //获取URL信息，以便平凑HTTP HEADER
$port = isset($url_array['port'])? $url_array['port'] : 80;
$fp = fsockopen($url_array['host'], $port, $errno, $errstr, 30);
if (!$fp) {
return FALSE;
$getPath = $url_array['path'] ."?". $url_array['query'];
$header = $method . " " . $getPath;
$header .= " HTTP/1.1\r\n";
$header .= "Host: ". $url_array['host'] . "\r\n"; //HTTP 1.1 Host域不能省略
$header .= "Connection:Close\r\n\r\n";
fwrite($fp, $header);
//echo fread($fp, 1024); //我们不关心服务器返回. 关闭这里才不会阻塞
fclose($fp);
return true;
function writelog($message) {
$path = './log.txt';
$handler = fopen($path, 'w+b');
if ($handler) {
$success = fwrite($handler, $message);
fclose($handler);

在php-fpm fastcgi下，也可以用fastcgi_finish_request实现异步非阻塞。
