php在迭代循环时回显结果

I am execution loop and inside loop there is data processing function inside loop.

  for($i = 0 ; $i <=680 ; $i = $i + 40)
    {
          $url = 'http://www.yelp.com/biz/franchino-san-francisco?start=80';
          $root = yelp($url);
          var_dump($root);
    }

This loop takes long time to execute, and results are echoed at the end when entire loop completes.

How can I echo the result during each iteration?

Actually what happens here? does to result are stored in buffer and at the end echoed or what?

    PHP buffers the output.

    If you want to output stuff to the browser immediately you can use the flush() and ob_flush() functions:

    for ($i = 0; $i <= 680; $i += 40) {
        $url = 'http://www.yelp.com/biz/franchino-san-francisco?start=80';
        $root = yelp($url);
        var_dump($root);
        flush();
        ob_flush();
    }
