+registerClass()

+register a class for use in the templates
+
+Description

+void
+
+registerClass

+
+Smarty allows you to access static classes from templates as long as the
+[Security Policy](#advanced.features.security) does not tell it
+otherwise. If security is enabled, classes registered with
+`registerClass()` are accessible to templates.
+
+
+    <?php
+
+    class Bar {
+      $property = "hello world";
+    }
+
+    $smarty = new Smarty();
+    $smarty->registerClass("Foo", "Bar");
+
+       
+
+
+    {* Smarty will access this class as long as it's not prohibited by security *}
+    {Bar::$property}
+    {* Foo translates to the real class Bar *}
+    {Foo::$property}
+
+       
+
+
+    <?php
+    namespace my\php\application {
+      class Bar {
+        $property = "hello world";
+      }
+    }
+
+    $smarty = new Smarty();
+    $smarty->registerClass("Foo", "\my\php\application\Bar");
+
+       
+
+
+    {* Foo translates to the real class \my\php\application\Bar *}
+    {Foo::$property}
