Question

I have a php web application that I am doing some testing on. This application is running on a Freebsd host. In the application directory, I have several .php files that I am not sure what/when they are used. Is there a way it log when this .php file is accessed by the application, and what arguments are passed to it, when it is used?

Answer 1

Sure. You can just put an error_log() call at the beginning of each file, assuming that you have accessing to whatever logs they will be written to (typically webserver error logs).

$error_msg = 'File: ' . __FILE__ . ' Request: ' . var_export($_REQUEST, true);
error_log($error_msg);

That will log the file being accessed, and and export of the Request superglobal so you know what is in GET, POST, and COOKIE.
