Many are provided by the shell under which PHP is running and different systems are likely running different kinds of shells, a definitive list is impossible. Please see your shell's documentation for a list of defined environment variables. Other environment variables include the CGI variables, placed there regardless of whether PHP is running as a server module or CGI proces- sor. $HTTP_ENV_VARS contains the same initial information, but is not a superglobal.
