通过display方法输出
    想分配变量可以使用assign方法

方法调用模板：C层调用V层




模板不存在[./Home/Tpl/Index/index.html]



<!doctype html>
<html lang="en">
 <head>
  <meta charset="UTF-8">
  <meta name="Generator" content="EditPlus?">
  <meta name="Author" content="">
  <meta name="Keywords" content="">
  <meta name="Description" content="">
  <title>Document</title>
 </head>
 <body>
  <h1>scan hello world!!!</h1>
 </body>
</html>


C控制V页面输出


寻找模板的规律:
Index模块/index方法

C:\wamp\www\thinkphp\Home\Tpl\Index\index.html
                              模块名\方法名



访问show方法:
<!doctype html>
<html lang="en">
 <head>
  <meta charset="UTF-8">
  <meta name="Generator" content="EditPlus?">
  <meta name="Author" content="">
  <meta name="Keywords" content="">
  <meta name="Description" content="">
  <title>Document</title>
 </head>
 <body>
  <h1>访问show!!!</h1>
 </body>
</html>

<?php
 class IndexAction extends Action {
   function index(){
     $name='scan';
     $this->assign('data',$name);
     $this->display();
   }
   


将$name分配给标识 data



分配给前台模板:
<!doctype html>
<html lang="en">
 <head>
  <meta charset="UTF-8">
  <meta name="Generator" content="EditPlus?">
  <meta name="Author" content="">
  <meta name="Keywords" content="">
  <meta name="Description" content="">
  <title>Document</title>
 </head>
 <body>
  <h1>{$data} hello world {$data}!!!</h1>
 </body>
</html>


{$data} hello world {$data} 花括号的意思:

定界符:

<?php
return array(
  //'配置项'=>'配置值'
  'TMPL_L_DELIM'=>'<{',   //配置左定界符
  'TMPL_R_DELIM'=>'}>',    //配置右定界符
  'DB_PREFIX'=>'',     //设置表前缀
  'DB_DSN'=>'mysql://root:1234567@10.10.17.2:3306/devops', //DSN方式配置数据库信息
  'SHOW_PAGE_TRACE'=>true,//开启页面Trace
);
?>


修改定界符:

mysql> show create table user\G;
*************************** 1. row ***************************
       Table: user
Create Table: CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(30) DEFAULT NULL,
  `sex` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
1 row in set (0.00 sec)



<?php
return array(
  //'配置项'=>'配置值'
  'TMPL_L_DELIM'=>'<{',   //配置左定界符
  'TMPL_R_DELIM'=>'}>',    //配置右定界符
  'DB_PREFIX'=>'',     //设置表前缀
  'DB_DSN'=>'mysql://root@127.0.0.1:3306/thinkphp', //DSN方式配置数据库信息
  'SHOW_PAGE_TRACE'=>true,//开启页面Trace
);
?>



array (size=2)
  0 => 
    array (size=3)
      'id' => string '1' (length=1)
      'username' => string 'zhaotongzhen' (length=12)
      'sex' => string '0' (length=1)
  1 => 
    array (size=3)
      'id' => string '2' (length=1)
      'username' => string 'mm' (length=2)
      'sex' => string '1' (length=1)

hello world


<?php
 class IndexAction extends Action {
   function index(){
     $m=new Model('user');
     $arr=$m->select();
     var_dump($arr[0]['username']);
     $this->assign('data',$name);
     $this->display();
   }
   
   function show(){
     $this->display();
   }
}
?>
