PHP函数从两个数组中获取差异元素

Question

Here's the situations: I have 2 arrays, eg:

$a=array('a','b','c','d');
$b=array('1','b','c','e');

I want to produce 2 arrays with result:

$c=array('a','d');//only element appeared on $a
$d=array('1','e');//only element appeared on $b

Do you have a clever solution?

Answer 1

$c = array_diff($a, $b);
$d = array_diff($b, $a);
