安装Smarty过程：
1 下载并且解压
2 将libs文件夹复制到目录/var/www/html
3 在/var/www/html目录下新建Mysmarty文件夹
4 在Mysmarty文件夹下新建4个文件夹cache,templates,templates_c,configs
5 将templates,templates_c权限改为777
测试Smarty
1 在Mysmarty文件夹下面建立test.php,内容如下：
<?php
include("/var/www/html/libs/Smarty.class.php"); //包含smarty类文件
$smarty = new Smarty(); //建立smarty实例对象$smarty
$smarty->template_dir = '/var/www/html/Mysmarty/templates';
$smarty->compile_dir = '/var/www/html/Mysmarty/templates_c';
$smarty->config_dir = '/var/www/html/Mysmarty/configs';
$smarty->cache_dir = '/var/www/html/Mysmarty/cache';
$smarty->caching = false;
$smarty->left_delimiter = "<{";
$smarty->right_delimiter = "}>";
$smarty->assign("title", "test"); //进行模板变量替换
$smarty->assign("content","BBBBBBBXXXXXXXXXBBBBBBBBBBBB");
//编译并显示位于./templates下的index.tpl模板
$smarty->display("test.tpl"); //
?>
2 templates下建立test.tpl
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title><{$title}></title>
</head>
<body>
<{$content}>
</body>
</html>
