为什么我看到有人在php文件里用这种语法
比如在wordpress的模板里经常看到这样的语法
<?php if (have_post()): ?> <div>...</div> <?php endif; ?>
为什么还要像if (...):
和endif;
这样写?这是什么语法?为什么不用括号呢?

上下标签对应的逻辑语法约定俗成拿来做原生的模板语言
类似的还有
while(..): endwhile;
foreach(..): ... endforeach;
这种格式都使用在视图中,代码更加清晰,也适合前端开发人员查看

当一个页面需要工程师与设计师共同完成的时候,这种高可读性的语法更有利于团队的合作。
其实这种原生的可读性也不错呀!从可读性角度似乎比较牵强,,,当然不可否定的是每种模板都有其各自的语法风格。。。
流程控制的替代语法
PHP 提供了一些流程控制的替代语法,包括 if,while,for,foreach 和 switch。替代语法的基本形式是把左花括号({)换成冒号(:),把右花括号(})分别换成 endif;,endwhile;,endfor;,endforeach; 以及 endswitch;。
<?php if ($a == 5): ?> A is equal to 5 <?php endif; ?>
在上面的例子中,HTML 内容“A is equal to 5”用替代语法嵌套在 if 语句中。该 HTML 的内容仅在 $a 等于 5 时显示。
楼上正解,不过,这些代码看起来还是比较恶心

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,
