总体内容分为传值类型和方法，大概总体感觉如下。

传值类型:一个值，多个值，数组。
方法: with，view，compact
默认视图 test文件下index.blade.php

单个值的传递

with

public function index() {
  $test = "测试";
  return view('test.index')->with('test',$test);
}

view

public function index() {
    return view('test.index', ['test' => '测试']);
}

compact

public function index() {
  $test = "测试";
  return view('test.index',compact('test'));
}

---

多个值的传递

with

public function index() {
  return view('test.index')->with(["test1" => "测试1", "test2" => "测试2", "test3" => "测试3"]);
}

view

public function index() {
  return view('test.index', ['test1' => '测试1','test2' => '测试2','test3' => '测试3']);
}

compact

public function index() {
  $test_1 = "测试1";
  $test_2 = "测试2";
  $test_2 = "测试3";
  return view('test.index',compact('test_1','test_2' ,'test_3' ));
}

---

数组的传递

with

public function index() {
  $data = array( 'test1' => '测试1', 'test2' => '测试2', 'test3' => '测试3' );
  return view('test.index')->with($data);
}

view

public function index() {
  $data["test1"] = "测试1";
  $data["test2"] = "测试2";
  $data["test3"] = "测试3";
  return view('test.index',$data);
}

compact

//推荐此种方法
public function index() {
  $test_array = ["测试1","测试2", "测试2"];
  return view('test.index',compact('test_array'));
}
