Summarize the reserved variables of the Smarty template for future use.

The reserved variable {$ smarty} is a special variable that can be directly accessed in the template and does not need to be allocated from the PHP script.

{$ Smarty. get}, {$ smarty. post}, and so on are used to access the page request Variables. the main page request variables include get, post, cookies, server, enviroment, and session variables. For example, {$ smarty. server. SERVER_NAME} gets the server variable, {$ smarty. env. PATH} obtains the path of the system environment variable {$ smarty. request. password} obtains the compound variable of get/post/cookies/server/env.

{$ Smarty. ldelim} and {$ smarty. rdelim} are used to display the left and right separators currently in use.

{$ Smarty. now} is used to access the current timestamp. you can use the date_format regulator to format the output. for example, {$ smarty. now | date_format: "% Y-% m-% d % H: % M: % S"}. output format: 07:19:09

{$ Smarty. const} directly accesses PHP constants. for example, {$ smarty. const. _ FILE __} is equivalent to the _ FILE _ constant in php. of course, you can also access custom constants.

{$ Smarty. capture} can output the data in the {capture} .. {/capture} tag through {$ smarty. capture. name. For detailed usage of capture, refer to http://www.phpernote.com/php-template-framework/43.html

The {$ smarty. config} {$ smarty} variable can access the loaded config variable. Note that the page template must first load a variable similar to {config_load file = "web. conf "}. For example, {$ smarty. config. pageTitle} indicates {# pageTitle #}.

{$ Smarty. section} and {$ smarty. foreach} can access the attributes of the 'secure' and 'foreach' loops.

{$ Smarty. template} displays the name of the currently processed template.

{$ Smarty. version} displays the version number of the currently used smarty template engine.
