我有一个多朦胧。具有重复值的数组。我需要它在下拉列表中只显示每个值的一个值，而后者又用于搜索查询。索引在这里并不重要。 我尝试使用array_map，serialize，array_unique等，但无法正确使用它。有些价值总是出现两次。
我在php版本4.3.2上，所以不能使用该版本之后的功能。
数组如下所示：
阵 （
[1] => Array

[1] => 0,9

任何帮助都将不胜感激。

与其他子阵列相比，使每个子阵列都是唯一的（顺序很重要）：
$array = array_map('unserialize', array_unique(array_map('serialize', $array)));
仅使每个子数组中的值唯一：
$array = array_map('array_unique', $array);
答案 1 :(得分：0)
$array = array_map('unserialize', array_unique(array_map('serialize', $array)));
正是我所尝试的，并且来自同一个线程，但它出现了这样：
