這篇文章將為大家詳細講解有關如何在php中基于workerman實現一個定時任務,文章內容質量較高,因此小編分享給大家做個參考,希望大家閱讀完這篇文章后對相關知識有一定的了解。
1、定時函數為匿名函數(閉包)
use \Workerman\Worker; use \Workerman\Lib\Timer; require_once './Workerman/Autoloader.php'; $task = new Worker(); // 開啟多少個進程運行定時任務,注意多進程并發問題 $task->count = 1; $task->onWorkerStart = function($task) { // 每2.5秒執行一次 $time_interval = 2.5; Timer::add($time_interval, function() { echo "task run\n"; }); }; // 運行worker Worker::runAll();
2、定時函數為普通函數
require_once './Workerman/Autoloader.php'; use \Workerman\Worker; use \Workerman\Lib\Timer; // 普通的函數 function send_mail($to, $content) { echo "send mail ...\n"; } $task = new Worker(); $task->onWorkerStart = function($task) { $to = 'workerman@workerman.net'; $content = 'hello workerman'; // 10秒后執行發送郵件任務,最后一個參數傳遞false,表示只運行一次 Timer::add(10, 'send_mail', array($to, $content), false); }; // 運行worker Worker::runAll();
3、定時函數為類的方法
require_once './Workerman/Autoloader.php'; use \Workerman\Worker; use \Workerman\Lib\Timer; class Mail { // 注意,回調函數屬性必須是public public function send($to, $content) { echo "send mail ...\n"; } } $task = new Worker(); $task->onWorkerStart = function($task) { // 10秒后發送一次郵件 $mail = new Mail(); $to = 'workerman@workerman.net'; $content = 'hello workerman'; Timer::add(10, array($mail, 'send'), array($to, $content), false); }; // 運行worker Worker::runAll();
4、定時函數為類方法(類內部使用定時器)
require_once './Workerman/Autoloader.php'; use \Workerman\Worker; use \Workerman\Lib\Timer; class Mail { // 注意,回調函數屬性必須是public public function send($to, $content) { echo "send mail ...\n"; } public function sendLater($to, $content) { // 回調的方法屬于當前的類,則回調數組第一個元素為$this Timer::add(10, array($this, 'send'), array($to, $content), false); } } $task = new Worker(); $task->onWorkerStart = function($task) { // 10秒后發送一次郵件 $mail = new Mail(); $to = 'workerman@workerman.net'; $content = 'hello workerman'; $mail->sendLater($to, $content); }; // 運行worker Worker::runAll();
5、定時函數為類的靜態方法
require_once './Workerman/Autoloader.php'; use \Workerman\Worker; use \Workerman\Lib\Timer; class Mail { // 注意這個是靜態方法,回調函數屬性也必須是public public static function send($to, $content) { echo "send mail ...\n"; } } $task = new Worker(); $task->onWorkerStart = function($task) { // 10秒后發送一次郵件 $to = 'workerman@workerman.net'; $content = 'hello workerman'; // 定時調用類的靜態方法 Timer::add(10, array('Mail', 'send'), array($to, $content), false); }; // 運行worker Worker::runAll();
6、定時函數為類的靜態方法(帶命名空間)
namespace Task; require_once './Workerman/Autoloader.php'; use \Workerman\Worker; use \Workerman\Lib\Timer; class Mail { // 注意這個是靜態方法,回調函數屬性也必須是public public static function send($to, $content) { echo "send mail ...\n"; } } $task = new Worker(); $task->onWorkerStart = function($task) { // 10秒后發送一次郵件 $to = 'workerman@workerman.net'; $content = 'hello workerman'; // 定時調用帶命名空間的類的靜態方法 Timer::add(10, array('\Task\Mail', 'send'), array($to, $content), false); }; // 運行worker Worker::runAll();
7、定時器中銷毀當前定時器(use閉包方式傳遞$timer_id)
use \Workerman\Worker; use \Workerman\Lib\Timer; require_once './Workerman/Autoloader.php'; $task = new Worker(); $task->onWorkerStart = function($task) { // 計數 $count = 1; // 要想$timer_id能正確傳遞到回調函數內部,$timer_id前面必須加地址符 & $timer_id = Timer::add(1, function()use(&$timer_id, &$count) { echo "Timer run $count\n"; // 運行10次后銷毀當前定時器 if($count++ >= 10) { echo "Timer::del($timer_id)\n"; Timer::del($timer_id); } }); }; // 運行worker Worker::runAll();
8、定時器中銷毀當前定時器(參數方式傳遞$timer_id)
require_once './Workerman/Autoloader.php'; use \Workerman\Worker; use \Workerman\Lib\Timer; class Mail { public function send($to, $content, $timer_id) { // 臨時給當前對象添加一個count屬性,記錄定時器運行次數 $this->count = empty($this->count) ? 1 : $this->count; // 運行10次后銷毀當前定時器 echo "send mail {$this->count}...\n"; if($this->count++ >= 10) { echo "Timer::del($timer_id)\n"; Timer::del($timer_id); } } } $task = new Worker(); $task->onWorkerStart = function($task) { $mail = new Mail(); // 要想$timer_id能正確傳遞到回調函數內部,$timer_id前面必須加地址符 & $timer_id = Timer::add(1, array($mail, 'send'), array('to', 'content', &$timer_id)); }; // 運行worker Worker::runAll();
9、只在指定進程中設置定時器
一個worker實例有4個進程,只在id編號為0的進程上設置定時器。
use Workerman\Worker; use Workerman\Lib\Timer; require_once './Workerman/Autoloader.php'; $worker = new Worker(); $worker->count = 4; $worker->onWorkerStart = function($worker) { // 只在id編號為0的進程上設置定時器,其它1、2、3號進程不設置定時器 if($worker->id === 0) { Timer::add(1, function(){ echo "4個worker進程,只在0號進程設置定時器\n"; }); } }; // 運行worker Worker::runAll();
示例
shipments.php用來寫定時任務
<?php use Workerman\Worker; use \Workerman\Lib\Timer; require_once "Workerman/Autoloader.php"; require_once "Connection.php"; $task = new Worker(); $task->onWorkerStart = function ($task) { global $db, $redis; $db = new \Workerman\MySQL\Connection('127.0.0.1', '3306', 'root', 'root', 'test'); $redis = new Redis(); $redis->connect('127.0.0.1', 6379); $redis->auth("qqq123123."); $time_interval = 0.1; Timer::add($time_interval, function () { global $db, $redis; $insert['name'] = 123; $db->insert('shipments')->cols($insert)->query(); // sleep(100); }); }; function curlGet($url = '', $options = []) { $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 30); if (!empty($options)) { curl_setopt_array($ch, $options); } //https請求 不驗證證書和host curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); $data = curl_exec($ch); curl_close($ch); return $data; } function newGetOrderInfo($taobao, $orderId) { $taobao = urlencode($taobao); $url = "http://114.55.144.79/taobao/TradeFullinfoGetRequest.php?shop=$taobao&tid=$orderId"; $json = curlGet($url); return json_decode($json, true)['trade']; } Worker::runAll();
