Bug #14472: predefined variables update

From: philip@cornado.com Operating system: n/a PHP version: 4.1.0 PHP Bug Type: Documentation problem Bug description: predefined variables update The "Predefined Variables" section of the manual needs some work, here are some thoughts: (a) Document that register_globals affects environment variables. For example, if register_globals is turned off then to access DOCUMENT_ROOT one needs to do $HTTP_SERVER_VARS['DOCUMENT_ROOT'] as $DOCUMENT_ROOT will not work. Also, use of getenv() is available, and now $_SERVER... This is an important point. Removing the $ in the description <term>'s seems appropriate too (b) Link to security.registerglobals (c) Link commandline to commandline docs (d) Remove specific reference to php3/apache 1.3.6 (e) List new 4.1.0 variables, keep seperate from the others (for now) (f) Mention of register_argc_argv near $argc & $argv (g) Expand docs on difference between ENV and SERVER variables (h) Add a See also: predefined constants and getenv() (i) Briefly document the affect of variable scope (j) Mention $GLOBALS (k) Between SCRIPT_NAME, PATH_INFO, PHP_SELF and REQUEST_URI, which are available when (cgi vs. mod) and why windows users sometimes get php.exe (l) Go through user notes, implement/delete as appropriate Related doc bugs are #11833, #14093 and #14260 -- Edit bug report at: http://bugs.php.net/?id=14472&edit=1
