PHP模板引擎Smarty之配置文件在模板变量中的使用方法示例_php实例
这篇文章主要介绍了PHP模板引擎Smarty之配置文件在模板变量中的使用方法,结合实例形式分析了配置文件变量的具体使用步骤与相关技巧,需要的朋友可以参考下
本文实例讲述了PHP模板引擎Smarty之配置文件在模板变量中的使用方法。分享给大家供大家参考，具体如下：
配置文件在模板中的作用是：给前端设计页面定义变量，主要控制的是模板的外观，与 PHP 程序无关。
使用步骤：
1、使用 $tpl->configs_dir="目录" //指定配置文件存放的目录；
2、在模板中要使用 <{configs_load file="配置文件"}> 加载f配置文件，如果有区域的话，可以使用 section="区域" 来指定区域
设置区域的目的是：为了不同的文件调用不同区域的配置文件变量。
在配置文件中是通过“[区域名称]”来指定区域的，其他没有指定区域的变量均为共有变量，即每一个页面都可以使用。
3、在指定的目录下建立配置文件。
下面通过一个实例来演示，实例思路：主文件 index.php 调用模板文件 index.tpl，在 index.tpl 中设置配置文件变量（与 PHP 程序无关）
init.inc.php Smart模板引擎初始化文件
<?php
define('ROOT_PATH', dirname(__FILE__)); //网站根目录
require ROOT_PATH.'/libs/Smarty.class.php'; //引入 Smart 模板引擎
$_tpl = new Smarty(); //初始化一个对象
$_tpl->template_dir = ROOT_PATH.'/tpl/'; //重新设置网站的模板目录
$_tpl->compile_dir = ROOT_PATH.'./com/'; //重新设置网站的编译文件目录
$_tpl->config_dir = ROOT_PATH.'/configs/'; //重新设置网站的配置文件目录
$_tpl->left_delimiter = '<{'; //重新设置网站的左定界符
$_tpl->right_delimiter = '}>'; //重新设置网站的右定界符
?>index.php
<?php require 'init.inc.php'; //引入模板初始化文件 global $_tpl; $_tpl->display('index.tpl'); //载入模板文件 ?>
index.tpl 配置变量的使用方式有两种：
一、<{#配置变量#}>；
二、<{$smart.config.配置变量}>
<{config_load file="view.conf" section="one"}>
<!-- view.conf文件不能写完整路径，因为在初始化文件中已经指定,section="one" 代表加载[one]区域 -->

</html>/configs/view.conf 配置文件
border=2 tabw=600 tabh=500 bgcolor=yellow align=center [one] colspan=4 aa=one section [two] bb=two section [three] cc=three section
执行结果，如图所示：
