  • PHP Smarty增删改查(考试题库)

    配置文件 init.inc.php

    <?php
define("ROOT",str_replace("\","/",dirname(__FILE__)).'/'); //常量ROOT中指定项目根目录(常量的名称,常量的值)
//当前文件的目录，不包含文件名 dirname(__FILE__))

require ROOT.'libs/Smarty.class.php'; //加载Smarty类文件

$smarty = new Smarty(); //实例化Smarty对象<br>

//设置初始路径
//$smarty -> auto_literal = false; //就可以让定界符号使用空格
$smarty->setTemplateDir(ROOT.'templates/'); //设置所有模板文件存放位置
//$smarty->addTemplateDir(ROOT.'templates2/'); //添加一个模板文件夹
$smarty->setCompileDir(ROOT.'templates_c/'); //设置编译过的模板存放的目录
$smarty->addPluginsDir(ROOT.'plugins/'); //设置为模板扩充插件存放目录
$smarty->setCacheDir(ROOT.'cache/'); //设置缓存文件存放目录
$smarty->setConfigDir(ROOT.'configs/'); //设置模板配置文件存放目录

$smarty->caching = false; //设置Smarty缓存开关功能
$smarty->cache_lifetime = 60*60*24; //设置缓存模板有效时间一天
$smarty->left_delimiter = '<{'; //设置模板语言中的左结束符
$smarty->right_delimiter = '}>'; //设置模板语言中的右结束符
