Requirements

PHP5.4+

Hello World

1. Put HelloWorld.php in your-project-dir/apis/

   /**
    * @path("/hw")
    */
   class HelloWorld
   {
       /** 
        * @route({"GET","/"})
        */
       public function doSomething() {
           return ['msg'=>'Hello World!'];
       }
   }

2. open http://your-domain/hw/

   {
       "msg":"Hello World!"
   }

What happened

See HelloWorld.php, the annotations like @path，@route are used to define routers. Phprs also use annotations for two-way parameter binding, dependency injection, etc.

Examples

"orders manage"

/**
 * @path("/orders/")
 */
class Orders
{
    /** 
     * @route({"GET","/"})
     * @return({"body"})
     */
    public function getAllOrders() {
        return Sql::select('*')->from('orders')->get($this->db);
    }
    /** 
     * @route({"GET","/*"})
     * @param({"id", "$.path[1]"})
      * @return({"body"})
     */
    public function getOrderById($id) {
        return Sql::select('*')->from('orders')->where('id=?',$id)->get($this->db);
    }
    
    /** 
     * @route({"POST","/"})
     * @param({"goods_info", "$._POST.goods"})
     * @return({"body"})
     */
    public function createOrder($goods_info){
        $order_id = Sql::insertInto('orders')->values($goods_info)->exec($this->db)->lastInsertId();
        return ['order_id'=>$order_id];
    }
    /**
     * Instance of class \PDO
     * @property 
     */
    public $db;
}

Features

1. Flexible routes

   PHPRS use @route to define routes.

   @route({"GET","/patha"})                  |   GET     | /patha, /patha/...
   ------------------------------------------+-----------+---------------------
   @route({"*","/patha"})                    |   GET     | /patha
                                             |   POST    |
                                             |   PUT     |
                                             |   DELETE  |
                                             |   HEAD    |
                                             |   ...     |
   ------------------------------------------+-----------+---------------------
   @route({"GET","\patha\*\pathb"})          |   GET     | /patha/xxx/pathb
   ------------------------------------------+-----------+---------------------
   @route({"GET","\func1?param1=1&param2=2"})|   GET     | /func1?param1=1&param2=2&...
                                             |           | /func1?param2=2&param1=1&...
   

2. Two-way parameter binding

   Annotations: @param, @return,@throws is used to bind variables between function parameters and http request or response.

   ------------------------------------------+-----------------------------
   @param({"arg0","$._GET.arg0"})            | $arg0 = $_GET['arg0']
   ------------------------------------------+-----------------------------
   @param({"arg1","$.path[1]"})              | $arg1 = explode('/', REQUEST_URI)[1]
   ------------------------------------------+-----------------------------
   @return({"cookie","token","$arg2"})       | setcookie('token', $arg2)
   function testCookie(&$arg2)               |
   ------------------------------------------+-----------------------------
   @return({"body"})                         | use function return as http response body
   ------------------------------------------+-----------------------------
   @throws({"MyException",                   | try{}
       "res",                                | catch(MyException) {
       "400 Bad Request",                    |   header('HTTP/1.1 400 Bad Request');
       {"error":"my exception"}})            |   body('{"error":"my exception"}');
                                             | }
   

3. Api cache

   Use @cache to enable cache for this method. If all params of the method are identical, the following calls will use cache.

    ----------------------------------+-----------------------------
    @cache({"ttl",3600})              | set cache as fixed time expire, as ttl 1 hour.
    ----------------------------------+-----------------------------
    @cache({"checker", "$checker"})   | Use dynamic strategy to check caches. 
                                      | $checker is set in method, and will be invoked to check cache expired with $checker($data, $create_time), for examples use $check = new FileExpiredChecker('file.tmp'); to make cache invalidated if file.tmp modified.
   

4. Dependency Injection

   Use @property to inject dependency phprs create API class and inject dependency from conf.json, which is looks like

   {
      "Orders":{
           "properties": {
               "db":"@db"
           }
      },
      "db":{
           "singleton":true,
           "class":"PDO",
           "pass_by_construct":true,
           "properties":{
               "dsn":"mysql:host=127.0.0.1;dbname=testdb;",
               "username":"test",
               "passwd":"test"  		
           }
      }
   }

5. Document automatic generation

   The document is looked like:

6. Hook

   The implement of a hook is the same as API.

7. ezsql

   An easy-to-use and IDE friendly SQL builder. Object-oriented SQL. @see https://github.com/caoym/ezsql

   $db = new \PDO($dsn, $username, $passwd);
   $res = Sql::select('a, b')
   ->from('table')
   ->leftJoin('table1')->on('table.id=table1.id')
   ->where('a=?',1)
   ->groupBy('b')->having('sum(b)=?', 2)
   ->orderBy('c', Sql::$ORDER_BY_ASC)
   ->limit(0,1)
   ->forUpdate()->of('d')
   ->get($db);

TODO

1. Inject Remote service support
2. User-defined annotations
3. Graceful auto document
