Question

我正在使用以下php编码从一长串视频ID中随机选择一个视频。我想要做的是在观看视频后从阵列中删除视频ID。我应该更具体一点。阵列中有256个视频ID。页面加载时随机选择一个视频ID，然后询问视频。我想要发生的是在观看视频后，用户按下“随机”按钮。刚刚观看的视频将从阵列中删除，并随机选择另一个视频。我不希望视频ID从阵列中永久删除，但暂时删除，因此他们不会随机获取相同的视频。

Answer 2

如果您的数组如下所示：

  $videolist = array('1' => 'video1','2' => 'video2');

观看视频后

：

unset($videolist[$value]);

Answer 3

你需要分两步完成......

$videoswatched = array(); // Create this in global area
$videolist = array('1' => 'video1','2' => 'video2');

shuffle($videolist);
$prefix = array_pop(array_diff($videolist, $videoswatched));
array_push($videoswatched, $prefix);
next($videolist);

从数组中删除变量
