Automatically run php files

这篇文章主要介绍了PHP文件的自动运行方法,分析了两种自动刷新的方法及相应的优缺点,需要的朋友可以参考下

本文实例分析了PHP文件的自动运行方法。分享给大家供大家参考,具体如下:

这里分析两种方法:

第一种方法:

a.php文件内容 如下:

<?php 
 ini_set("error_log", "c:\php\php_error.log"); 
 error_log("a.php is execute----------",0); 
 ignore_user_abort(); // 后台无阻断运行 
 set_time_limit(0); // 一直给我运行 
 $zhoz_execute_time = 30; // 运行时间seconds,这里设置成一分钟跑一次。 
 do { 
  // 这里想执行什么都可以写了 
  error_log("a is do !!!!----------",0); 
  sleep($zhoz_execute_time); // 按指定轨道时间运行 
 } while (true); 
?>

但这里有个缺点,需要先运行一下这个PHP文件,如通过url运行:http://www.php.cn/

这里只要执行一次就可以了,然后关闭页面。

另外,当Apache/IIS重启后,这个脚本就不会执行了。

为此,我又想到了另外一个方法:

在cmd下运行:

php-win.exe -c "c:\php\php.ini" -f C:\Apache2.2\htdocs\a.php

(这里也只要运行一次,运行多了时间会缩短运行的。)

这样的话,即使怎么重启Apache/IIS这个脚本仍然会运行的。
还有缺点:重启机器或杀死进程php-win.exe,当然它就不能跑了……
这个解决办法,可以添加启动项里作成bat应该是可以完美解决!

第二种方法:

b.php内容:

<?php
  $fp=fopen("c:\\test\\a.txt","a+");
  fwrite($fp,"测试\r\n");
  fclose($fp);
?>

然后写一个bat文件,在其中写入:

c:\php\php -c c:\php\php.ini -f c:\Apache2.2\htdocs\b.php

保存

然后使用那个at 命令将其加入的计划任务中

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2.
