ThinkPHP
第一个是import标签 ,导入方式采用类似ThinkPHP的import函数的命名空间方式,例如:
import标签(采用命名空间方式引入资源文件) |
|
闭合 |
闭合标签 |
属性 |
file(必须):要引入的资源文件,支持变量 type(可选):引入的资源文件类型,默认为js,支持js css和php basepath(可选):命名空间的基础路径 |
示例:
Type属性默认是js, 所以下面的效果是相同的:
还可以支持多个文件批量导入,例如:
导入外部CSS文件必须指定type属性的值,例如:
上面的方式默认的import的起始路径是网站的Public目录,如果需要指定其他的目录,可以使用basepath属性,例如:
第二个是load标签,通过文件方式导入当前项目的公共JS或者CSS
load标签(采用url方式引入资源文件) |
|
闭合 |
闭合标签 |
属性 |
href(必须):要引入的资源文件url地址,支持变量 |
例如:
在href属性中可以使用特殊模板标签替换,例如:
Load标签可以无需指定type属性,系统会自动根据后缀自动判断。
系统还提供了两个标签别名js和css 用法和load一致,例如:

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.

It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
