Smarty comes with several built-in functions.
Built-in functions are integral to the template language.
You cannot create custom functions with the same names, nor can you modify built-in functions.

capture

capture is used to collect the output of the template into a variable instead of displaying it.
Any content between {capture name="foo"} and {/capture} is collected into the variable specified in the name attribute.
The captured content can be used in the template from the special variable $smarty.
capture.foo where foo is the value passed in the name attribute. If you do not supply a name attribute, then "default" will be used.
All {capture} commands must be paired with {/capture}. You can nest capture commands.

�ռ�����Ϣ���������������$smarty��.
����capture.foo���ռ�����������.�������û����������,��ʹ��"default".
ÿ��{capture}�������Ӧ{/capture},Ҳ����Ƕ��ʹ��capture����

Technical Note:
Smarty 1.4.0 - 1.4.4 placed the captured content into the variable named $return.
As of 1.4.5, this behavior was changed to use the name attribute, so update your templates accordingly.

Caution

Be careful when capturing {insert} output. If you have caching turned on and you have {insert} commands that you expect to run within cached content, do not capture this content.
