THINKPHP的cron任務實現

THINKPHP的cron任務實現

thinkphp的cron計劃任務的實現,利用THINKPHP自帶的cli,加上數據庫執行記錄(記錄任務的報錯,成功)。

在服務器cron定時任務在網站目錄(不是網站根目錄)執行php cron.php,網站根目錄為Public。

THINKPHP的cron任務實現

寫一個cli的入口文件

cli.php

<?php define(&#39;MODE_NAME&#39;, &#39;cli&#39;); // 檢測PHP環境 if(version_compare(PHP_VERSION,&#39;5.3.0&#39;,&#39;<&#39;))  die(&#39;require PHP >?5.3.0?!');  define('APP_DEBUG',?true);  //?定義應用目錄 define('APP_PATH',?__DIR__?.?'/Application/');  //?引入ThinkPHP入口文件 require?__DIR__?.?'/ThinkPHP/ThinkPHP.php';

寫一個執行文件

cron.php

define('AUTO_CRON',?true); include?__DIR__?.?'/cli.php';

tdcron_entry.php

<?php /**  * tinyCronEntry is part of tdCron. Its a class to parse Cron-Expressions like "1-45 1,2,3 1-30/5 January,February Mon,Tue"  * and convert it to an easily useable format.  *  * The parser is quite powerful and understands pretty much everything you will ever find in a Cron-Expression.  *  * A Cron-Expression consists of 5 segments:  *  * <pre class="brush:php;toolbar:false">  *  .---------------- minute (0 - 59)  *  |   .------------- hour (0 - 23)  *  |   |   .---------- day of month (1 - 31)  *  |   |   |   .------- month (1 - 12)  *  |   |   |   |  .----- day of week (0 - 6)  *  |   |   |   |  |  *  *   *   *   *  *  * 

* * Each segment can contain values, ranges and intervals. A range is always written as “value1-value2” and * intervals as “value1/value2”. * * Of course each segment can contain multiple values seperated by commas. * * Some valid examples: * *

  * 1,2,3,4,5  * 1-5  * 10-20/*  * Jan,Feb,Oct  * Monday-Friday  * 1-10,15,20,40-50/2  * 

* * The current version of the parser understands all weekdays and month names in german and english! * * Usually you won't need to call this class directly. * * Copyright (c) 2010 Christian Land / tagdocs.de * * Permission is hereby granted, free of charge, to any person obtaining a copy of this software and * associated documentation files (the “Software”), to deal in the Software without restriction, * including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, * subject to the following conditions: * * The above copyright notice and this permission notice shall be included in all copies or substantial * portions of the Software. * * THE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT * LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
