php smarty框架的初步使用和注意事项

1.什么是模板引擎
    两个部分比较关心
    1.1就是GUI(视图,界面)    --HTML CSS JAVASCRIPTE
    1.2是业务逻辑(php编码)    --PHP MYSQL
    
    模板引擎是使用php开发的一个项目
    
2.Smarty
    2.1安装
        1.解压,只用到libs目录,需要使用Smarty.class.php和插件文件夹
        2.创建文件夹:templates和template_c文件夹(默认文件夹名)
        3.创建php文件(见例子)
            include "./libs/Smarty.class.php";
            设置替换内容,设置显示模板
        4.访问
    2.2Smarty初始化
        1.初始化可以在Smarty.class.php中修改制定值
        2.在php页面调用的时候初始化
            //解决问题:Warning: strftime() [function.strftime]:
            date_default_timezone_set("Asia/Shanghai");
            include "./libs/Smarty.class.php";
            $tpl = new Smarty();
            //smarty初始化
            $tpl->template_dir="./templates/";
            $tpl->compile_dir="./template_c/";
            $tpl->left_delimiter="";
        
    2.3Smarty使用注意事项
        1.查找资源(css/js/image)
            资源文件放在访问的php页面对应的资源位置(因为访问时模板是被包含在php文件当中的)
        2.所有的display模板时(还是include),都要指定Smarty模板中的指定的基路径

        3.模板目录之外的php引用smarty文件时,将Smarty的初始文件换成绝对路径

示例代码:

init.smarty.php

 

<?php define(ROOT, "");

	//解决问题:Warning: strftime() [function.strftime]:
	date_default_timezone_set("Asia/Shanghai");
	include ROOT."./libs/Smarty.class.php";
	
	$tpl = new Smarty();
	
	//smarty初始化
	$tpl->template_dir=ROOT."./templates/";
	$tpl->compile_dir=ROOT."./template_c/";
	$tpl->left_delimiter="<!--{";
	$tpl->right_delimiter="}-->";
	?>


mysmarty.php

 

<?php //如果文件加载失败require会停止继续解析php;而include则会继续向下执行
	require 'init.smarty.php';
	//程序简单方式
	$title="这是一个文字标题,从数据库中获取";
	$content = "这是内容";
	
	$tpl->assign("title",$title);
	$tpl->assign("content",$content);
	//模板文件名可以随便定义:比如:mysmarty.tpl只有内容是html就可以了
	$tpl->display("mysmarty.html");
?>


mysmarty.html



<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title><!--{$title}--></title>


<!--{$content}-->
