如何使用for打印多维数组？

Question

我正在尝试使用以下代码从多维数组中打印信息：

$url = $_POST['fromtheformandworking'];
$urls_array = get_headers($url,1);

$count_location = count($urls_array["Location"]);

for ($i=0; $i > $count_location ; $i++) { 
echo $urls_array["Location"]["$i"];
}

它没有返回任何东西。有谁知道我哪里做错了？感谢。

你的for循环中有错误，应该是

for ($i=0; $i < $count_location ; $i++) { 
          echo $urls_array["Location"]["$i"];
      }
