关于数组处理的有关问题，

关于数组处理的问题，急
$a=array("郑秀文","郭涛","华仔","高圆圆","王子义","郎月婷","刘德华")
$b=array("华仔","刘德华")

用B数组过滤掉$b数组中的重复

输出的效果为：
Array
(
[0] => 郑秀文
[1] => 郭涛
[2] => 高圆圆
[3] => 王子义
[4] => 郎月婷
)
------解决方案--------------------

$a = array("郑秀文","郭涛","华仔","高圆圆","王子义","郎月婷","刘德华");
$b = array("华仔","刘德华");
print_r(array_diff($a, $b));

Array
(
[0] => 郑秀文
[1] => 郭涛
[3] => 高圆圆
[4] => 王子义
[5] => 郎月婷
)
