使用PHP4中的 IntegratedTemplate类实现BLOCK功能
使用PHP 模板类进行编程很有好处，但是有时也会碰到一个问题，比如说输出一个表格，但是表格行数要到运行的时候才知道，如留言板、BBS、购物网站之类，经常会碰到这个问题。这时做美工的人无法决定在HTML文件中用几行表格，如果在PHP代码文件中写循环输出，又会让美工、PHP程序员看代码都不方便，美工的人会说，这里的表格哪里去了？我要修改表格的颜色背景之类怎么办？PHP程序员也会说，怎么这里突然有一个
使用PHP模板类编程一般把这种不确定个数的HTML 元素当成一个“ block ”，对 bolck 的编程类似于在代码中写一个循环。在比较常用的PHP模板类（如 FastTemplate 和 PHPLib ）都有这种功能。写嵌套的block 类似于写多重循环。现在举例说明在 PHP4 里面的 IntegratedTemplateExtension 类中block 的编程方法，例子中用的是两重循环，外层block 是GoodsList，里层block 是GoodsListOfSomeType 。
基本设置：假设我们写的代码放在C:TestPHPPHP4GoodsList.htm 和 C:TestPHPHTMLGoodsList.php 中。将C:TestPHPPHP4 在Web Server 上设成虚拟目录 /testphp 并且给与脚本执行权限，确认C:TestPHPHTMLGoodsList.htm 无法通过远端浏览器访问。假定PHP4安装在C:php4，在 php.ini 里面设置 include_path = ".;C:php4pear"
以下是GoodsList.htm的内容：

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
