mysql 数据迁移问题,所有的.frm文件报错·
从另一吧机子把数据库目录文件全部拷贝到本机,数据表都能看到,但查询或看结构时报错:
#1033 - Incorrect information in file: 'xxx.frm'
------解决方案--------------------
你的存储引擎是什么?
如果是 MyISAM 则表文件由 *.FRM, *.MYD, *.MYI 组成,把这三个文件都复制到相关的数据库目录下即可。
如果是innoDB的,则*.FRM仅包含表的定义,数据文件在 ibdata1 中,你需要把原来的 idbdata1, ib_logfile0,ib_logfile1 或者还有其它文件一都复制过来

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.
