Question

我有一个场景：

有些div正在显示基于以下循环：

  <?php foreach($posts->content as $entry) { ?>
   <div><a class="popup-with-zoom-anim wiplay" id="<?=$entry->id?>"
   href="#small-dialog" data-detail-id ="<?=$entry->id?>"
   data-stream="******">content here</a></div>
   <?php } ?>

在a href＆＃34;数据流＆＃34;我想传递一些youtube网址，所以每个div将显示基于for循环的随机网址。我尝试了以下代码。但是没有工作。我们如何在循环中调用此函数？

$assoc_array = array( "url" => "https://www.youtube.com
/watch?v=A7XdOyZIkko", 
        "url" => "https://www.youtube.com/watch?v=dMH0bHeiRNg

  ", 
        "url" => "https://www.youtube.com/watch?v=xEs59zTXu7s", 
        "url" => "https://www.youtube.com/watch?v=tlDAgZO2ZDM
  ");
  function shuffle_assoc_array(&$array) {
  if (!is_array($array)) return $array;
  $keys = array_keys($array);
  shuffle($keys);
  $random = array();
  foreach ($keys as $key)
    $random[$key] = $array[$key];
  $array = $random;   return TRUE;
  }
   shuffle_assoc_array($assoc_array);

如何将此youtube网址随机传递给for循环？

Answer 1

这个数组只给你一个值

array( 
"url" => "https://www.youtube.com
/watch?v=A7XdOyZIkko", 
"url" => "https://www.youtube.com/watch?v=dMH0bHeiRNg", 
"url" => "https://www.youtube.com/watch?v=xEs59zTXu7s", 
"url" => "https://www.youtube.com/watch?v=tlDAgZO2ZDM
");

这相当于

array( 
    "url" => "https://www.youtube.com/watch?v=tlDAgZO2ZDM
");

尝试这样的事情

array( 
"https://www.youtube.com/watch?v=A7XdOyZIkko", 
"https://www.youtube.com/watch?v=dMH0bHeiRNg", 
"https://www.youtube.com/watch?v=xEs59zTXu7s", 
"https://www.youtube.com/watch?v=tlDAgZO2ZDM"
);

正如Ima所说，你必须要改变你的数组格式，而不是尝试下面的代码。

<?php
   $assoc_array = array( "https://www.youtube.com/watch?v=A7XdOyZIkko", "https://www.youtube.com/watch?v=dMH0bHeiRNg", "https://www.youtube.com/watch?v=xEs59zTXu7s", "https://www.youtube.com/watch?v=tlDAgZO2ZDM");

   shuffle($assoc_array);

   for($i=0;$i<count($assoc_array);$i++){
      echo '<div><a class="popup-with-zoom-anim wiplay" id="'.$i.'" href="#small-dialog" data-detail-id ="'.$i.'" data-stream="'.$assoc_array[$i].'">'.$assoc_array[$i].'</a></div>';
   }
?>

如何在php中的for循环中将随机url添加到href？
