PHP实现定时任务（非linux-shell方式，与操作系统无关）

栏目: 编程语言 · PHP · IT技术 · 发布时间: 6年前

内容简介：用PHP实现定时任务（非linux-shell方式，与操作系统平无关）。适用于定时精确时间不低于1秒。web服务重启、或者php重启。该定时任务不会自动重启。可以用来处理大部分定时任务的结局方案，商城定时自动收货，关闭评论，订单回滚；定时发送邮件，数据备份等

页面交互效果

下面是写好的示例前端交互页面，主要是列表页面，编辑页面。

主要交互有：

1 开启定时任务进程
2 关闭定时任务进程
3 新增一项定时任务
4 编辑已有的定时任务
5 删除定时任务
6 开始一项定时任务
7 停止一项定时任务

定时任务分两种：

1 执行一次
2 循环执行

定时任务执行的内容：

定时任务执行的内容其实还是一个http请求。通过定时的方式，指定时间执行或者循执行。

1 列表页面

2 新建\编辑页面

代码地址，演示地址

示例代码是基于Laravel，Alpaca-spa框架编写，并且作为 ‘Alpaca-Spa-Laravel后台管理平台’的一个模块儿集成于系统中。

代码： http://git.oschina.net/cc-sponge/Alpaca-Spa-Laravel

代码： https://github.com/big-sponge/Alpaca-Spa-Laravel

适用范围

定时精确时间不低于1秒。web服务重启、或者 php 重启。该定时任务不会自动重启。

实现原理

用PHP实现定时任务（非linux-shell方式，与操作系统平台无关），主要两个技术点：

1）PHP后台进程
2）PHP异步处理

1 PHP后台进程

一般情况，用命令行可以开启一个php后台进程。而在浏览器中通过HTTP请求一个php处理，会因为浏览器关闭，或者请求超时，使得后台的php处理中断。但是php提供了两个方法可以会忽略浏览器关闭、请求超时：

ignore_user_abort(true);     // 忽略客户端断开
set_time_limit(0);           // 设置执行不超时

1 2	ignore_user_abort(true); // 忽略客户端断开 set_time_limit(0); // 设置执行不超时

因此，我们可以使用这两个函数从浏览器以HTTP请求的方式开启一个php后台进程。

2 PHP异步处理

php语言本身没有可以跨平台好用异步处理方法，但是可以通过curl或者fsockopen创建一个请求来实现异步处理。这里我们用fsockopen方法实现：

$fp = fsockopen("$ip", $port, $errno, $errstr,1);
        if (!$fp) {
            return 'worker error:'."$errstr ($errno)<br />\n";
        } else {
            $out = "POST $url HTTP/1.1\r\n";
            $out .= "Host: $ip\r\n";
            $out .= "Content-Type:application/x-www-form-urlencoded; charset=UTF-8\r\n";
            $out .= "Content-Length: " . strlen($postData) . "\r\n";
            $out .= "Connection: close\r\n";
            $out .="\r\n";
            $out .=$postData;
            fputs($fp, $out);
            fclose($fp);
        }

$fp = fsockopen("$ip", $port, $errno, $errstr,1);

if (!$fp) {

return 'worker error:'."$errstr ($errno)<br />\n";

} else {

$out = "POST $url HTTP/1.1\r\n";

$out .= "Host: $ip\r\n";

$out .= "Content-Type:application/x-www-form-urlencoded; charset=UTF-8\r\n";

$out .= "Content-Length: " . strlen($postData) . "\r\n";

$out .= "Connection: close\r\n";

$out .="\r\n";

$out .=$postData;

fputs($fp, $out);

fclose($fp);

}

前台交互控制器

为了在前端界面方便控制定时任务的开启关闭，新增、编辑、删除，查看执行状态。同时也可以添加权限控制。主要有8个操作接口(下面是以 Laravel 路由示例)：

1 查看定时任务进程状态
2 开始定时任务进程 3 停止定时任务进程
4 添加,或者编辑定时任务
5 设置定时任务状态
6 获取指定定时任务明细
7 删除定时任务
8 获取定时任务列表

/* crontab - status 查看定时任务守护进程状态 */
Route::any('crontab/status', "CrontabController@status");

/* crontab - start 开始定时任务 */
Route::any('crontab/start', "CrontabController@start");

/* crontab - stop  停止定时任务守护进程*/
Route::any('crontab/stop', "CrontabController@stop");

/* crontab - editTask  添加,或者编辑定时任务*/
Route::any('crontab/editTask', "CrontabController@editTask");

/* crontab - changeTaskStatus  设置定时任务状态 */
Route::any('crontab/changeTaskStatus', "CrontabController@changeTaskStatus");

/* crontab - getIndexTask  获取指定定时任务 */
Route::any('crontab/getIndexTask', "CrontabController@getIndexTask");

/* crontab - removeTask  删除定时任务 */
Route::any('crontab/removeTask', "CrontabController@removeTask");

/* crontab - listTask  获取定时任务列表 */
Route::any('crontab/listTask', "CrontabController@listTask");

/* crontab - status 查看定时任务守护进程状态 */

Route::any('crontab/status', "CrontabController@status");

/* crontab - start 开始定时任务 */

Route::any('crontab/start', "CrontabController@start");

/* crontab - stop 停止定时任务守护进程*/

Route::any('crontab/stop', "CrontabController@stop");

/* crontab - editTask 添加,或者编辑定时任务*/

Route::any('crontab/editTask', "CrontabController@editTask");

/* crontab - changeTaskStatus 设置定时任务状态 */

Route::any('crontab/changeTaskStatus', "CrontabController@changeTaskStatus");

/* crontab - getIndexTask 获取指定定时任务 */

Route::any('crontab/getIndexTask', "CrontabController@getIndexTask");

/* crontab - removeTask 删除定时任务 */

Route::any('crontab/removeTask', "CrontabController@removeTask");

/* crontab - listTask 获取定时任务列表 */

Route::any('crontab/listTask', "CrontabController@listTask");

实现后台进程类

使用 ignore_user_abort(true); set_time_limit(0); 可以从浏览器开启一个php后台进程。为了避免出现多个后台进程，需要借助一个配置来标识该后台进程是否已经启动

{"code":"1001","message":"Stop at:2017-02-24 11:29:43"}

1	{"code":"1001","message":"Stop at:2017-02-24 11:29:43"}

当code是1001时候，表示后台进程未启动，这时通过http请求开启后台进程时，正常启动

当code是1000时候，表示后台进程已经启动，这时通过http请求开启后台进程时，不做任何操作，以为进程已经启动

当开启后台进程的请求到达后台时候，读取配置文件，如果code是1001，则启动进程，并且设置code为1000，保存配置文件。

当关闭后台进程的请求到达后台时候，读取配置文件，设置code为1001，保存配置文件。

后台进程在运行时候，每隔一秒读取配置文件，判断code状态，如果是1001，则结束执行；如果是1000，则继续执行

定时任务处理类

定时任务处理类主要是实现新增、编辑、删除定时任务，执行定时任务要处理的方法

定时任务的信息以json格式存放在下面的配置文件中

[{"NAME":"\u6d4b\u8bd5\u5b9a\u65f6\u4efb\u52a12","STATUS":"2","TYPE":"1","INTERVAL":"5 second","BEGIN_TIME":"2017-02-21 11:55:00","NEXT_TIME":"2017-02-21 11:55:00","LAST_TIME":null,"ACTION":"\/main\/crontab\/index2","END_TIME":"2017-02-10 15:55:00"},{"NAME":"TEST - log","STATUS":"2","TYPE":"2","INTERVAL":"5 second","BEGIN_TIME":"2017-08-10 09:00:53","NEXT_TIME":"2017-08-10 09:59:00","LAST_TIME":"2017-08-10 09:58:55","ACTION":"\/crontab\/task\/test","END_TIME":"2017-08-11 09:25:53"}]

[{"NAME":"\u6d4b\u8bd5\u5b9a\u65f6\u4efb\u52a12","STATUS":"2","TYPE":"1","INTERVAL":"5 second","BEGIN_TIME":"2017-02-21 11:55:00","NEXT_TIME":"2017-02-21 11:55:00","LAST_TIME":null,"ACTION":"\/main\/crontab\/index2","END_TIME":"2017-02-10 15:55:00"},{"NAME":"TEST - log","STATUS":"2","TYPE":"2","INTERVAL":"5 second","BEGIN_TIME":"2017-08-10 09:00:53","NEXT_TIME":"2017-08-10 09:59:00","LAST_TIME":"2017-08-10 09:58:55","ACTION":"\/crontab\/task\/test","END_TIME":"2017-08-11 09:25:53"}]

主要的字段为：

INDEX 索引
BEGIN_TIME 开始时间
END_TIME 结束时间
INTERVAL 时间间隔
NAME 名称
STATUS 状态 1-ENABLED, 2-DISABLE
TASK_TYPE 类型 1-ONCE, 2-LOOP
ACTION 要执行的Action

类中主要有7个方法：

listTask() 查看定时任务列表 addTask() 添加定时任务 editTask() 编辑定时任务 editTaskStatus() 编辑定时任务状态 getIndexTask() 获取指定定时任务信息 removeTask() 删除定时任务 doTask() 执行定时任务指定的任务
