删除3天以前的日志文件,Fatal error
我不懂PHP,现在想实现一个功能,删除指定目录中三天以前的文件(日志),就在百度上找的一个删除目录的函数,如下
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> function del_directory($dir){ if(!($mydir = @dir($dir))){ return; } while($file = $mydir->read()){ if(is_dir("$dir$file") && $file!='.' && $file!='..'){ @chmod("$dir$file", 0777); del_dir("$dir$file"); }elseif(is_file("$dir/$file")){ $file_time=@stat($file);//读取文件的最后更新时间 if(time() - $file_time > 3600 * 24 * 3){ @chmod("$dir/$file", 0777); @unlink("$dir/$file"); } } } $mydir->close(); @chmod($dir, 0777); @rmdir($dir); }
报错:Fatal error: Unsupported operand types in D:\wamp\www\Player\playlogviewer.php on line 36
对应的是这一行代码:if(time() - $file_time > 3600 * 24 * 3)
麻烦看看是什么问题,谢谢!

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
