从非关联数组

Question

下面的代码删除非唯一的PHP数组值：

$ids=['one','two','three','two','four']; 
echo('<pre>'.print_r($ids,1).'</pre>'); 
$ids = array_unique($ids); 
echo('<pre>'.print_r($ids,1).'</pre>'); 

产生如下：

Array 
(
    [0] => one 
    [1] => two 
    [2] => three 
    [3] => two 
    [4] => four 
) 

Array 
(
    [0] => one 
    [1] => two 
    [2] => three 
    [4] => four 
) 

如何保持连续数组索引并产生如下：

Array 
(
    [0] => one 
    [1] => two 
    [2] => three 
    [3] => four 
)

再添加一个线 array_values($ids)
