$_SERVER["QUERY_STRING"]=\\获取?号后面的内容
$_SERVER["REQUEST_URI"]=例子:/lianxi/servervalues.php?a=1&b=2
$_SERVER["SCRIPT_NAME"]=例子:/lianxi/servervalues.php
$_SERVER["PHP_SELF"]=/lianxi/servervalues.php \\返回当前网页的相对路径.

$_SERVER存储当前服务器信息,其中有几个值 如$_SERVER["QUERY_STRING"],$_SERVER["REQUEST_URI"],$_SERVER["SCRIPT_NAME"] 和$_SERVER["PHP_SELF"]常常容易混淆,以下通过实例详解$_SERVER函数中 QUERY_STRING,REQUEST_URI,SCRIPT_NAME和PHP_SELF变量区别,掌握这四者之间的关系,便于在实际应用中正确获 取所需要的值,供参考。
1,$_SERVER["QUERY_STRING"]
说明:查询(query)的字符串
2,$_SERVER["REQUEST_URI"]
说明:访问此页面所需的URI
3,$_SERVER["SCRIPT_NAME"]
说明:包含当前脚本的路径
4,$_SERVER["PHP_SELF"]
说明:当前正在执行脚本的文件名
实例:
1,http://www.biuuu.com/ (直接打开主页)
结果:
$_SERVER["QUERY_STRING"] = “”
$_SERVER["REQUEST_URI"] = “/”
$_SERVER["SCRIPT_NAME"] = “/index.php”
$_SERVER["PHP_SELF"] = “/index.php”
2,http://www.biuuu.com/?p=222 (附带查询)
结果:
$_SERVER["QUERY_STRING"] = “p=222″
$_SERVER["REQUEST_URI"] = “/?p=222″
$_SERVER["SCRIPT_NAME"] = “/index.php”
$_SERVER["PHP_SELF"] = “/index.php”
3,http://www.biuuu.com/index.php?p=222&q=biuuu
结果:
$_SERVER["QUERY_STRING"] = “p=222&q=biuuu”
$_SERVER["REQUEST_URI"] = “/index.php?p=222&q=biuuu”
$_SERVER["SCRIPT_NAME"] = “/index.php”
$_SERVER["PHP_SELF"] = “/index.php”
$_SERVER["QUERY_STRING"]获取查询语句,实例中可知,获取的是?后面的值
$_SERVER["REQUEST_URI"] 获取http://www.biuuu.com后面的值,包括/
$_SERVER["SCRIPT_NAME"] 获取当前脚本的路径,如:index.php
$_SERVER["PHP_SELF"] 当前正在执行脚本的文件名
总结一下,对于QUERY_STRING,REQUEST_URI,SCRIPT_NAME和PHP_SELF,深入了解将有利于我们 在$_SERVER函数中正确调用这四个值。通过实例详解$_SERVER函数中 QUERY_STRING,REQUEST_URI,SCRIPT_NAME和PHP_SELF掌握四个变量之间的区别。

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,
