如果要在使用array_unique（）后关闭键中的间隙，可以使用array_values（）。示例：

if you want to close the gaps into the keys after using array_unique() you can use array_values() afterwards. Example:

a = array("one", "two", "two", "three")
a = array_unique(a);
/* will lead to:
a[0] = "one"
a[1] = "two"
a[3] = "three"
*/
a = array_values(a);
/* Now we've got:
a[0] = "one"
a[1] = "two"
a[2] = "three"
*/
?>

希望这会有所帮助..
