从PHP分配的变量

Smarty - the compiling PHP template engine
Prev　来源：PHP中文社区		Next

Table of Contents[内容列表]
Associative arrays[关联数组]
Array indexes[数组下标]
Objects[对象]

Variables that are assigned from PHP are referenced by preceding them with a dollar sign $.
Variables assigned from within the template with the assign function are also displayed this way.

调用从PHP分配的变量需在前加"$"符号.（译注：同php一样）
调用模板内的assign函数分配的变量也是这样.（译注：也是用$加变量名来调用）

Example 4-1. assigned variables
例 4-1.分配的变量

index.php:

$smarty = new Smarty;
$smarty->assign("firstname", "Doug");
$smarty->assign("lastLoginDate", "January 11th, 2001");
$smarty->display("index.tpl");

index.tpl:

Hello {$firstname}, glad to see you could make it.
<p>
Your last login was on {$lastLoginDate}.

OUTPUT:

Hello Doug, glad to see you could make it.
<p>
Your last login was on January 11th, 2001.
