一、laravel路由（应用中的大多数路由都会定义在 app/routes.php 文件中）

routes.php

Route::get('/test','TestController@index');

一个路由就定义好了，当访问 http://xxx.com/public/index.php/test 时就会去找 app/controllers/TestController.php的index方法 TestController.php

class TestController extends Controller{        public function index(){                echo "hello world";    }}

一个控制器就建立好了，控制器也可以设置闭包，也可以设置别名

Route::get('user/profile', array('as' => 'profile', function(){    echo "hello world";}));

更多路由请看手册：

二、模型 

普通数据库操作

$results = DB::select('select * from users where id = ?', array(1));//查$results = DB::insert('insert into users (id, name) values (?, ?)', array(1, 'Dayle'));//增$results = DB::update('update users set votes = 100 where name = ?', array('John'));//更新$results = DB::delete('delete from users where id = ?',array(1));//删

查询生成器

//查$obj = DB::table('archives')->select('archives.*','arctype.typename')->where('archives.id','>',2)->join('arctype','arctype.id','=','archives.typeid','left')->orderBy('archives.id','desc')->skip(10)->take(5)->get();//查多条数据$obj = DB::table('archives')->where('typeid','=','1')->orderBy('id','desc')->first();//查询一条数据//where条件分组$sql = DB::table('archives')    ->where('typeid', '=', 1)    ->orWhere(function($query)    {        $query->where('id', '>', 2)                ->where('title', '<>', 'Admin');    })    ->get();//sql语句: select * from `la_archives` where `typeid` = 1 or (`id` > 2 and `title` <> 'Admin')//聚合查询$users = DB::table('archives')->count();//查总数$price = DB::table('archives')->max('id');//查最大值$price = DB::table('archives')->min('id');//查最小值$price = DB::table('archives')->avg('id');//查平均值$total = DB::table('archives')->sum('id');//查和//增$data = array('title'=>'标题八','body'=>'内容八','typeid'=>2);$obj = DB::table('archives')->insert($data);//改$data2 = array('title'=>'标题九','body'=>'内容九','typeid'=>2);$obj = DB::table('archives')->where('id',2)->update($data2);//删$obj = DB::table('archives')->where('id','>','100')->delete();

//模型（app/models/Archives.php）

class Archives extends Eloquent{        protected $table = 'archives';//表名    public $timestamps  = false;//不自动维护更新时间}

//模型操作和普通SQL查询一样

$arr = Archives::select('archives.*','arctype.typename')->where('archives.id','>',2)->join('arctype','arctype.id','=','archives.typeid','left')->orderBy('archives.id','desc')->skip(0)->take(10)->get();$data = array('title'=>'新标题','body'=>'新内容');$arr = Archives::where('id','=',2)->update($data);

三、视图（app/views/home/test.blade.php）

    $v){        echo $v->title.'
';    }?>

控制器中

public function test(){   $data = Archives::select('*')->get();   return View::make('home.test')->with('items',$data);}
