如何打印不同大小的关联数组

我在php中有这个关联数组。在这最后的指数有另一个数组...我试图打印ID，但无法做到plz帮助我呼应id的值如何打印不同大小的关联数组

array (size=1) 
    2 => 
    array (size=8) 
     'id' => int 32 /// this is I want to echo 
     'uid' => int 2 
     'title' => string ' a type s' (length=9) 
     'price' => int 555555 
     'cat' => string 'Car' (length=3) 
     'usage' => string 'used' (length=4) 
     'desc' => string 'which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum gen' (length=200) 
     'img' => 
     array (size=2) 
      'img_id' => int 2 
      'img_name' => string 'image_2014-09-18-22-10-59_541b3c53b5e12.jpeg' (length=44)

数组变量名是$广告。

 $ad_set = Array (
        'id' => $id, /// Want to echo this 
        'uid' => $uId, 
        'title' => $title, 
        'price' => $price, 
        'cat' => $cat, 
        'usage' => $usage, 
        'desc' => $desc, 
        'img' => $a_img 
      ); 
      try { 
       $ads [$count] = $ad_set; 
      } catch (Exception $exc) { 
       echo $exc->getTraceAsString(); 
      } 

      $count ++; 
    return $ads;

'回声$广告[2] [ 'IMG'] [ 'img_id']' – Ghost 2014-09-19 15:58:38

没有我试图仅回显'id'索引... – Umerm 2014-09-19 15:59:53

很简单。抓住数组'$ ad_set'，然后获取数组中的索引，'[2]'，然后获取您之后的键值，'['id']'。 – Ohgodwhy 2014-09-19 16:02:28

对不起，问题是在逻辑..计数器递增多个times..thanks求助
