Here are some of the sorting, PHP to get the path of the small knowledge, hope to help you!

1,$_server["query_string") Description: Query string 2,$_server["Request_uri"] Description: The uri3,$_server["Script_name" required to access this page Description: Contains the path of the current script 4,$_server["php_self" description: The file name of the currently executing script

　　

Demo:1
http://www.xxx.com/(open homepage directly) results: $_server["query_string"] = "$_server[" Request_uri "] ="/"$_server[" script_name "] ="/ index.php "$_server[" php_self "] ="/index.php "

Demo:2
Http://www.xxx.com/?p=1 (with Query) results: $_server["query_string"] = "p=1" $_server["request_uri"] = "/?p=1" $_server["Script_ NAME "] ="/index.php "$_server[" php_self "] ="/index.php "

Demo 3
Http://www.xxx.com/index.php?p=1&q=xxx Result: $_server["query_string"] = "p=1&q=xxx" $_server["request_uri"] = " /index.php?p=1&q=xxx "$_server[" script_name "] ="/index.php "$_server[" php_self "] ="/index.php "

$_server["Query_string"] gets the query statement, in the instance, gets the following value $_server["Request_uri"] gets the value after http://www.xxx.com, including/$_server[" Script_name "] Gets the path to the current script, such as: index.php $_server[" Php_self ") the file name of the currently executing script

Current URL: "/http". $_server[' http_host '].$_server[' php_self ']

To summarize, for Query_string,request_uri,script_name and php_self, deep understanding will help us to correctly invoke these four values in the $_server function. The differences between the four variables are mastered by Query_string,request_uri,script_name and php_self in the $_server function by example.

$_server["Request_uri"]: Gets the full "except domain name" URL for the current request
