The example of this article summarizes the usage of several predefined variables $_server in PHP. Share to everyone for your reference. Specifically as follows:
Copy Code code as follows:
<?php
Echo ' DocumentRoot: '. $_server[' document_root '. ' <br> '; The root directory, defined in the Apache configuration file: httpd.conf For example: DocumentRoot "D:/work/php_root"
Echo ' Httphost: '. $_server[' http_host '. ' <br> '; Domain name, such as: localhost
Echo ' phpself: '. $_server[' php_self '. ' <br> '; The path from the root directory to the file itself
echo ' script filename '. $_server[' script_filename '. ' <br> '; Documentroot+phpself
echo ' request URI '. $_server[' Request_uri '. ' <br> '; Start all URL strings from the root directory, including characters after question marks
Echo ' request method: '. $_server[' Request_method '. ' <br> '; Method of Request
Echo ' name: '. $_request[' name '. ' <br> '; The value of the request parameter
?>
