php中smarty变量修饰用法实例分析
这篇文章主要介绍了php中smarty变量修饰用法,实例分析了smarty模板变量修饰的常用技巧,需要的朋友可以参考下。
本文实例讲述了php中smarty变量修饰用法,分享给大家供大家参考,具体实现方法如下:
test.php代码:
- <?php
- require 'libs/Smarty.class.php'; //包含Smarty类库文件
- $smarty = new Smarty; //创建一个新的Smarty对象
- $total = 12345; //对$total赋值
- $smarty->assign("total",$total); //对模版中的变量赋值
- $formatted_total = number_format($total); //格式化$total
- $smarty->assign("formatted_total",$formatted_total); //对模版中的变量赋值
- $smarty->display('test1.htm'); //显示页面
- ?>
test1.html模板代码:
- <html>
- <head>
- <title>Smarty Test</title>
- </head>
- <body>
- <H1>Total is {$total}</H1>
- <H1>Formatted Total is {$formatted_total}</H1>
- </body>
- </html>
编译后的test.html.php代码:
- <?php /* Smarty version 2.6.22, created on 2009-03-19 14:37:39
- compiled from test1.htm */ ?>
- <html>
- <head>
- <title>Smarty Test</title>
- </head>
- <body>
- <H1>Total is <?php echo $this->_tpl_vars['total']; ?>
- </H1>
- <H1>Formatted Total is <?php echo $this->_tpl_vars['formatted_total']; ?>
- </H1>
- </body>
- </html>
test1.html模板可以改写成这样test2.html:
- <html>
- <head>
- <title>Smarty Test</title>
- </head>
- <body>
- <H1>Total is {$total}</H1>
- <H1>Formatted Total is {$total|number_format}</H1>
- </body>
- </html>
则相应的test.php代码改为:
- <?php
- require 'libs/Smarty.class.php'; //包含Smarty类库文件
- $smarty = new Smarty; //创建一个新的Smarty对象
- $total = 12345;
- $smarty->assign("total",$total); //对模版中的变量赋值
- $smarty->display('test2.htm'); //显示页面
- ?>
浏览器显示:
Total is 12345
Formatted Total is 12,345
