 ====== Global Variables ======
-:!: // This page refers to VuFind 1.x; newer versions of VuFind do not rely on global variables at all. //
+// As of release 2.0, VuFind no longer relies on global variables. This outdated page has been deleted to prevent confusion. To view old content for historical interest, see the "Old Revisions" list below. //
-VuFind uses a few important global variables that you may find helpful when [[legacy:vufind_1.x_developer_manual:building_a_module|building modules]] and maintaining the code.
-===== Primary Globals =====
-These two globals are the most important, and their use is encouraged:
-  * $configArray \\ This global contains the contents of the web/conf/config.ini file mapped into associative array format.
-  * $interface \\ This global is an instance of the UInterface class, used for passing information to the Smarty presentation layer.  See the [[legacy:vufind_1.x_developer_manual:system_classes|System Classes]] page for more details.
-===== Secondary Globals =====
-These globals are used in the code in a few places, but their use should be avoided unless absolutely necessary:
-  * $translator \\ This global is an instance of the I18N_Translator class, used for translating presentation-layer text into various languages.  This should be needed only rarely outside of the presentation templates.
-  * $user \\ This global is an object representing the current logged-in user, if one exists.  User login code may be refactored, so use this sparingly.
-===== Accessing a Global =====
-Remember that in PHP, you need to declare globals at the top of any functions or methods that use them.  For example:
-<code php>
-function dumpConfigArray()
-{
-    global $configArray;
-    print_r($configArray);
-}
