thinkphp5.1 模板赋值与变量输出 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([
      'sex' => '男',
      'salary' => 1200
    ]);
 
    //2、array
    $this->view->assign('goods',[
      'id' => 1,
      'name' => '手机',
      'model' => 'meta10',
      'price' => 3000
    ]);
 
    //3、object
    $obj = new \stdClass();
    $obj->course = 'PHP';
    $obj->lecture = 'zhang';
    $this->view->assign('info',$obj);
 
    //4、const(系统常量)
    define('SITE_NAME','PHP');
 
    //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();
  }
