郁闷的问题,rename在foreach中不执行,
当rename($kb,$newfile.$dimg);在foreach外面的时候是执行的,
但是到了foreach里面就不行了,哪位大神讲解下?到底是咋了。怎么解决!
$hkt=$db->get_one("select fid,attachmentdomain,attachmentdir from news_sort where fid='$fid'"); $postdb[content]=str_replace("http://www_mydomain.com","../../".$attachmentdir,$postdb[content]); $newfile="../../upload_files/".$hkt[attachmentdir]."/"; preg_match_all("/<[img|IMG].*?src=[\\\'|\\\"][^http](.*?(?:[\.gif|\.jpg]))[\\\'|\\\"].*?[\/]?>/i",$postdb[content],$imglist); foreach($imglist[1] as $kb){ $kb=str_replace("\"","",$kb); $dimg=explode("/",$kb); $dimg=$dimg[count($dimg)-1]; $kbimg=$hkt[attachmentdomain]."/".$dimg; $postdb[content]=str_replace($kb,$kbimg,$postdb[content]); rename($kb,$newfile.$dimg); unlink($kb); }
回复讨论(解决方案)
循环中打印出来$kb,$newfile,$dimg等分别是什么。
要学会一步一步跟踪调试
均以测试了的!就是在foreach中不行。。 下面的unlink都执行了,就是rename不执行!
循环中打印出来$kb,$newfile,$dimg等分别是什么。
要学会一步一步跟踪调试
$kb=老的图片路径,“../../img/A.jpg”
$newfile=新储存路径,"../../newimg/"
$dimg=是图片的名称:"a.jpg"
搞定了! 呼呼 ! $newfile不是绝对路径所致!

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.
