本文实例讲述了Smarty变量用法。分享给大家供大家参考，具体如下：
1. 从PHP分配的变量
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）
示例:
index.php:
$smarty = new Smarty;
$smarty->assign('firstname', 'Doug');
$smarty->assign('lastLoginDate', 'January11th, 2001');
$smarty->display('index.tpl');
index.tpl:
Hello {$firstname}, glad to see you couldmake it.
<p>
Your last login was on {$lastLoginDate}.
输出:
Hello Doug, glad to see you could make it. <p> Your last login was on January 11th, 2001.
2. 从配置文件读取的变量
配置文件中的变量需要通过用两个"#"或者是smarty的保留变量 $smarty.config.来调用（后面会讲到）
第二种语法在变量作为属性值并被引号括住的时候非常有用.
（译注：举个例子 {include file="#includefile#"} 这样#includefile#将被当作字符处理，而不表示配置文件变量，但可以这样表示{include file="`$smarty.config.includefile`"}不要忘了加``）
示例:
foo.conf:
pageTitle = "This is mine" bodyBgColor = "#eeeeee" tableBorderSize = "3" tableBgColor = "#bbbbbb" rowBgColor = "#cccccc"
index.tpl:
{config_load file="foo.conf"}
<html>
<title>{#pageTitle#}</title>
<body bgcolor="{#bodyBgColor#}">
<table border="{#tableBorderSize#}" bgcolor="{#tableBgColor#}">
<tr bgcolor="{#rowBgColor#}">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
index.tpl:
{config_load file="foo.conf"}
<html>
<title>{$smarty.config.pageTitle}</title>
<body bgcolor="{$smarty.config.bodyBgColor}">
<table border="{$smarty.config.tableBorderSize}"bgcolor="{$smarty.config.tableBgColor}">
<tr bgcolor="{$smarty.config.rowBgColor}">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
上述两种模板写法都输出:
<html>
<title>This is mine</title>
<body bgcolor="#eeeeee">
<table border="3" bgcolor="#bbbbbb">
<tr bgcolor="#cccccc">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
配置文件的变量只有在它们被加载以后才能使用.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
