What I want to know is, if I declare variable global - > is it global for current session or all sessions? I know about It is global for the current invocation of the script (and all code included from it). To make variables global between all invocations/scripts in a given session, you need to use the session management functions of PHP4. Look at the manual and search phpbuilder.com for some intro on that. > And one thing more. What EXACTLY means php configuration value: > register_global? If set to "on", PHP automatically generates global vars from values passed via GET/POST requests and cookies. Example: calling http://foo.bar/test.php?answer=42 will call test.php with a global variable $answer set to "42" -- Christian Reiniger LGDC Webmaster (http://sunsite.dk/lgdc/) Nothing is more dangerous than an idea if it's the only one you have. - Emil-Auguste Chartier, "Propos sur la religion", 1938
