Summary of pre-reserved variables in php smarty

The following is an example of accessing page request variables such as get, post, cookies, server, environment and session variables. For example, {$smarty.server.SERVER_NAME} obtains server variables, {$smarty.env.PATH} obtains system environment variables path, { $smarty.request.username} obtains the composite variable of get/post/cookies/server/env.
{$smarty.now} variable is used to access the current timestamp.
You can use the date_format adjuster to format the output. For example {$smarty.now|date_format:"%Y-%m-%d %H:%M:% S"}
{$smarty.const}
You can directly access PHP constants. For example, {$smarty.const._MY_CONST_VAL}

The output can be captured through the {capture}..{/capture} structure It can be accessed using the {$smarty} variable.
