比如这个地址,我想得到红色区域的地址用于生成站内的链接,名为 baseurl。
用 $_SERVER['SCRIPT_NAME'] 就可以了, $_SERVER['SCRIPT_NAME'] 是当前正在访问的PHP文件的相对路径,只要如下稍作处理:
//从$_SERVER['SCRIPT_NAME']中获取目录部分,并且替换dirname函数可能出现的反斜杠问题 ??
$baseUrl?=?str_replace('\\','/',dirname($_SERVER['SCRIPT_NAME'])); ?
//保证为空时能返回可以使用的正常值 ?
$baseUrl?=?empty($baseUrl)???'/'?:?'/'.trim($baseUrl,'/').'/';??
这样就可以正常获取到 /dev/classd/ 这部分的目录地址了。
顺便看了一下 Zend Framework 的 baseUrl() 函数,结果一看那么一大堆代码就没再继续看了,我就想不通同样的功能他用了一大堆一大堆的代码,从$_SERVER里获取了一堆,然后中间经过两三个类,四五个方法才最终被我们直接调用,除了中间有三行是获取当前的PHP文件以外,其它都是没用和无谓的处理,ZF本身运行的已经够慢的了,这是什么一个意思呢。

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,
