+# count
+
+Returns the number of elements in an array (or Countable object). Will return 0 for null.
+Returns 1 for any other type (such as a string).
+
+If the optional mode parameter is set to 1, count() will recursively count the array. 
+This is particularly useful for counting all the elements of a multidimensional array.
+
+## Basic usage
+```smarty
+{if $myVar|count > 3}4 or more{/if}
+{if count($myVar) > 3}4 or more{/if}
+```
+
+
+## Parameters
+
+| Parameter | Type | Required | Description                                            |
+|-----------|------|----------|--------------------------------------------------------|
+| 1         | int  | No       | If set to 1, count() will recursively count the array. |
