: This article mainly introduces how to obtain the current url path and server path by PH (obtain the server path of the current path by url). If you are interested in the PHP Tutorial, refer to it. The following are some of the information. I hope to help you with the small knowledge of getting paths in php!
1, $ _
["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. T
