如题所述,php 伪静态不借助.htaccess怎么做,就是纯php能写吗

PHP只能处理PHP请求,像/post/1024这样的请求,如果Apache或者Nginx不通过重写rewrite把URI信息传给指定的PHP文件,那么PHP就不可能通过$_SERVER['REQUEST_URI']取到这个信息。如果你用的是PHP内置的CLI HTTP Server,倒是可以进行路由,在启动时指定路由文件,比如index.php:
https://wiki.php.net/rfc/builtinwebserver
php -S 127.0.0.1:8080 -t /www /www/index.php

<code><?php $url = parse_url($_SERVER['REQUEST_URI']);
$uri = $url['path'];
if (file_exists(dirname(__FILE__).$uri)) {
    return false; //如果请求的文件或目录存在,直接返回
} else {
    print_r($url); //分析URI,进行路由
}
</code></code>
Copy after login

上面这段PHP代码跟下面常用的采用index.php作为前端控制器(路由)的框架重写规则含义相近:

<code># Apache
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [QSA,L]

# Nginx
location / {
    try_files $uri $uri/ /index.php?$args;
}
</code>
Copy after login

url重写 - php 伪静态不借助.htaccess怎么做
你可以在每个需要重写的目录里面新建一个index.php.处理内容进行转发。
比如 要转发的地址 http://xxx.xxx.xxx/dirA/dirC/
在dirA中写一个index.php,手动转发给目的地。

PHP很多框架都有路由功能,会把url按照"/"拆分,解析出控制器、方法、参数,然后框架的控制程序就会调用对应的控制器的相应方法,并把参数传递过去。 当然参数多的时候只保持控制器和方法以目录分隔,其他参数还是能够以查询字符串的形式传递过去的。 可以看下CI框架的Router类。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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,
