Note Submitter: joe@heritagecreations.com ---- 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.
