Question

我生成了这样的数组。我如何访问返回的正文？我得到一个循环来获取数据值以接收此列表构建。我知道如何获得totalResults，但我无法深入了解数组。感谢。

foreach ($searchres as $videout){
echo '<li id="cNa9dzezrd8"><img src="http://i.ytimg.com/vi/cNa9dzezrd8/0.jpg"><br>';
echo '<div class="description">';
echo '<h3>Danny McCarthy - Silver Scrape...</h3>';
echo '<span>Author : </span> Kavvson<br>';
echo '<span>Views : </span> 161654<br>';
echo '</div></li>';
}

数组

array(4) {
  ["totalResults"]=>
  string(3) "588"
  ["startIndex"]=>
  string(1) "1"
  ["itemsPerPage"]=>
  string(1) "2"
  ["results"]=>
  array(2) {
    [0]=>
    array(12) {
      ["id"]=>
      string(11) "cNa9dzezrd8"
      ["title"]=>
      string(67) "Danny McCarthy - Silver Scrapes ( Extended culineR & Kavvson Edit )"
      ["description"]=>
      string(160) "SoundCloud : Original version : Danny McCarthy - Silver Scrapes Edited by culineR and Me {} culineR www.Facebook.com/devonculineR www.Sou..."

      string(19) "04/05/2013 00:20:51"

假设$arr拥有您的数组，然后尝试

foreach($arr['results'] as $ar){
  echo $ar['id']; // and so on
}

从多维数组中检索数据
