What’s the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? How do I use them?When I run print_r($_SERVER), PATH_INFO and ORIG_PATH_INFO are not present in the array. Why not? How can I enable them?I have read the PHP manual on them, but still don’t understand them. 解决方案 The PATH_INFO variable is only present if you invoke a PHP script like this:http://www.example.com/phpinfo.php/HELLO_THEREIt's only the /HELLO_THERE part after the .php script. If you don't invoke the URL like that, there won't be a $_SERVER["PATH_INFO"] environment variable.The PORIG_ prefix is somewhat uncommon. PATH_INFO is a standard CGI-environment variable, and should never be prefixed. Where did you read that? (There were some issues around PHP3/PHP4 if you invoked the PHP interpreter via cgi-bin/ - but hardly anyone has such setups today.)For reference: http://www.ietf.org/rfc/rfc3875 这篇关于$ _SERVER ['PATH_INFO']和$ _SERVER ['ORIG_PATH_INFO']有什么区别?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
