Slim 框架学习，第三天

紧接着第二天的内容

先上一段代码

public function offsetGet($id)
    {
        echo $id."
";
        if (!isset($this->keys[$id])) {
            throw new UnknownIdentifierException($id);
        }
        if (
            isset($this->raw[$id])
            || !is_object($this->values[$id])
            || isset($this->protected[$this->values[$id]])
            || !method_exists($this->values[$id], '__invoke')
        ) {
            return $this->values[$id];
        }
        if (isset($this->factories[$this->values[$id]])) {
            return $this->values[$id]($this);
        }
        echo $id.'1'."
";
        $raw = $this->values[$id];
        echo $id.'2'."
";
        $val = $this->values[$id] = $raw($this);
      //  die();
       // echo $id.'3'.'___';

        $this->raw[$id] = $raw;

        $this->frozen[$id] = true;
        echo "
";
        echo $id.'___';
        //var_dump($this->values);
        echo "
";
        die();
        return $val;
    }

返回结果让我很想不通

router
router1
router2
settings
settings1
settings2
settings___
为何传进去的是router，却执行了settings 。经过调试发现
val= this->values[ id]= raw($this);这一句，导致的原因，
但是为什么会出现这种情况，现在还没搞明白。

回到第一天的index.php 文件

require 'vendor/autoload.php';

$app = new Slim\App();

$app->get('/hello/{name}', function ($request, $response, $args) {
    return $response->write("Hello, " . $args['name']);
});
echo "
";
var_dump($app);
echo "
";die();
$app->run();

返回结果如下

[“container”:”Slim\App”:private]=>
object(Slim\Container)#3 (7) {

index.php 中的最后一行 $app->run(); 明天在进行探讨。
