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：
|
1
2
3
4
5
6
7
8
9
|
<?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
$smarty->display('test1.htm'); //显示页面
?>
|
test1.html模板代码：
|
1
2
3
4
5
6
7
8
9
|
<html>
<head>
<title>Smarty Test</title>
</head>
<body>
<H1>Total is {$total}</H1>
<H1>Formatted Total is {$formatted_total}</H1>
</body>
</html>
|
编译后的test.html.php代码：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
<?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 $this->_tpl_vars['formatted_total']; ?>
</H1>
</body>
</html>
|
test1.html模板可以改写成这样test2.html：
|
1
2
3
4
5
6
7
8
9
|
<html>
<head>
<title>Smarty Test</title>
</head>
<body>
<H1>Total is {$total}</H1>
<H1>Formatted Total is {$total|number_format}</H1>
</body>
</html>
|
则相应的test.php代码改为：
|
1
2
3
4
5
6
7
|
<?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
希望本文所述对大家的php程序设计有所帮助。
