分享如何判断两个数组中对应键的值相同的个数
假设有以下两个数组：
$arr1=array("A","B","A","C","C","A");
$arr1=array("A","A","A","B","C","A");
php里有没有办法快速判断出数组中键名相同对应值相同的数目？就是说可以判断出例子中有“4”个相同的方法....

$arr1 = array("A","B","A","C","C","A");
$arr2 = array("A","A","A","B","C","A");
$r = array_intersect_assoc($arr1, $arr2);
print_r($r);
Array
(
[0] => A
[2] => A
[4] => C
[5] => A
)
$arr2 = array("A","A","A","B","C","A");
$r = array_intersect_assoc($arr1, $arr2);
print_r($r);
Array
(
[0] => A
[2] => A
[4] => C
[5] => A
)
