note 32587 added to reserved.variables

Variables that you use in include files are automatically made global. If your include file has usernames and passwords assigned to a variable, those values are sitting in $GLOBALS. Accessing the include file from within a function will keep the variables local to the function so that they don't become globals. Also, when assigining a predefined (global) variable to a variable you created, the new variable is automatically made global. You don't need to pass the variable to a function, just declare it as global within the function and the function will access the value. function PrintRoot{ global $rootdirectory; print $rootdirectory; // displays /home/user/dir } $rootdirectory = $_SERVER['DOCUMENT_ROOT']; PrintRoot(); ... To view all the global variables: print '<pre>'; print_r($GLOBALS); PRINT '</pre>'; User variables are at the bottom of the list. ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+32587 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+32587&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+32587&report=yes
