thinkphp5.1框架模板赋值与变量输出示例

namespace app\index\controller;
use think\Controller;
use think\facade\View;
class Demo extends Controller
{
  public function test1()
  {
    //直接将内容输出到页面，不通过模板
    $con = '<h3 style="color:red" PHP</h3 ';
    return $this- dieplay($con);
    return $this- view- display($con);
    return View::display($con);//静态代理
  }
//使用视图将数据进行输出：fetch()

public function test2()

{

//模板变量赋值：assign()

//1、普通变量

$this- view- assign('name','zhang');

$this- view- assign('age',23);
//批量赋值
$this- view- assign([
  &#39;sex&#39; =  &#39;男&#39;,
  &#39;salary&#39; =  1200
]);

//2、array
$this- view- assign(&#39;goods&#39;,[
  &#39;id&#39; =  1,
  &#39;name&#39; =  &#39;手机&#39;,
  &#39;model&#39; =  &#39;meta10&#39;,
  &#39;price&#39; =  3000
]);

//3、object
$obj = new \stdClass();
$obj- course = &#39;PHP&#39;;
$obj- lecture = &#39;zhang&#39;;
$this- view- assign(&#39;info&#39;,$obj);

//4、const(系统常量)
define(&#39;SITE_NAME&#39;,&#39;PHP&#39;);

//在模板中输出数据
//模板默认的目录位于当前模块的view目录，模板文件默认位于以当前控制器命名的目录中
return $this- view- fetch();

}
