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
我尝试过array_diff_key和array_diff函数,但两者都只返回
Array()
I would like to get the count of the difference, is there a faster way?
我想得到差异的数量,有更快的方法吗?
What did i do wrong? Thank you very much for your help!

$array1 = array ( [34] => A [35] => B [36] => B [37] => C )
$array2 = array( [34] => B [35] => C [36] => A [37] => D )
$c = count(array_diff($array1, $array2));
echo $c;

You can use array_diff_assoc().
您可以使用array_diff_assoc()。
<?php
$array1 = array('34' => 'A', '35' => 'B', '36' => 'B', '37' => 'C');
$array2 = array('34' => 'B', '35' => 'C', '36' => 'A', '37' => 'D');
$count = count(array_diff_assoc($array1, $array2));
echo $count; //4
