比较php中两个数组的差异

Question

Array ( [34] => A [35] => B [36] => B [37] => C ) //This is the Answer

Compares

Array ( [34] => B [35] => C [36] => A [37] => D ) //This is the right data

I have tried array_diff_key and array_diff functions but both only returns

Array()

I would like to get the count of the difference, is there a faster way?

What did i do wrong? Thank you very much for your help!

Answer 1

count(array_diff_assoc($array1, $array2));
