About the problem with array processing,

On the problem of array processing, the urgent
$a =array ("Sammi Cheng", "Guo Tao", "Hua Zi", "Gao Yuan Yuan", "Wang Ziyi", "Lang", "Andy Lau")
$b =array ("Hua Zi", "Andy Lau")

Filter out duplicates in $b array with b array

The effect of the output is:
Array
(
[0] = Sammi Cheng
[1] = Guo Tao
[2] = high round
[3] = Wang Ziyi
[4] = Lang
)
------Solution--------------------

$a = Array ("Sammi Cheng", "Guo Tao", "Hua Zi", "Gao Yuan Yuan", "Wang Ziyi", "Lang", "Andy Lau");
$b = Array ("Hua Zi", "Andy Lau");
Print_r (Array_diff ($a, $b));

Array
(
[0] = Sammi Cheng
[1] = Guo Tao
[3] = high round
[4] = Wang Ziyi
[5] = Lang
)
