Example analysis of smart variable modification usage in php, smarty example analysis

The examples in this article describe the usage of smarty variable modification in php. Share it with everyone for your reference. The specific implementation method is as follows:

test.php code: 

<&#63;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 
&#63;>

test1.html template code: 

<html> 
  <head> 
    <title>Smarty Test</title> 
  </head> 
  <body> 
    <H1>Total is {$total}</H1> 
    <H1>Formatted Total is {$formatted_total}</H1> 
  </body> 
</html>

Compiled test.html.php code: 

<&#63;php /* Smarty version 2.6.22, created on 2009-03-19 14:37:39 
     compiled from test1.htm */ &#63;> 
<html> 
  <head> 
    <title>Smarty Test</title> 
  </head> 
  <body> 
    <H1>Total is <&#63;php echo $this->_tpl_vars['total']; &#63;> 
</H1> 
    <H1>Formatted Total is <&#63;php echo $this->_tpl_vars['formatted_total']; &#63;> 
</H1> 
  </body> 
</html>

The test1.html template can be rewritten as test2.html like this: 

<html> 
  <head> 
    <title>Smarty Test</title> 
  </head> 
  <body> 
    <H1>Total is {$total}</H1> 
    <H1>Formatted Total is {$total|number_format}</H1> 
  </body> 
</html>

Then the corresponding test.php code is changed to: 

<&#63;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 
&#63;>

Browser display:

Total is 12345
Formatted Total is 12,345
