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. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.

The article explains how to create, implement, and use interfaces in PHP, focusing on their benefits for code organization and maintainability.

The article discusses the differences between crypt() and password_hash() in PHP for password hashing, focusing on their implementation, security, and suitability for modern web applications.

Article discusses preventing Cross-Site Scripting (XSS) in PHP through input validation, output encoding, and using tools like OWASP ESAPI and HTML Purifier.
