<code>//读取数据库 $content=str_emoji(false,$content);</code>
下面问题来了。
iconv("UCS-2","UTF-8",pack("H4","\\1")) 不能将二进制专程UTF-8,怎么破????
另:数据库版本不能直接存储emoji,升级数据库是肯定不可行的方案。

存数据库的时候 base_encode64()
取得的时候base_decode64()
mysql编码选择utf8mb4即可
数据库是mysql吧,把数据库和字段编码设置为utf8mb4,可以直接保存表情字符

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.

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.
