all external URLs look like ‘module/action?key1=param1’. No customization possible–but it’s fast.
The difference is that the first uses PHP’s GET, and the second uses PATH_INFO.
PATH_INFO several times, but still don’t know what exactly it is. What does it do?
PATH_INFO is related to the Apache Web Server serving PHP pages and not PHP per se.
PATH_INFO is an environment variable set by Apache when the
AcceptPathInfo directive is turned on. It will contain trailing pathname information that follows an actual filename or non-existent file in an existing directory, whether the request is accepted or rejected. Environment variables are then passed on to the Apache/CGI module in charge of rendering the page.
The variable is accessible in PHP using
For example, assume the location
/test/ points to a directory that contains only the single file
here.html. Then requests for
/test/nothere.html/more both collect
As the variable PATH_INFO is part of the definition for CGI you should also take a look in there 😉
