比較在php×2個陣列的區別

Question

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

比較

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

我試圖array_diff_key和array_diff功能，但都只有回報

Array() 

我想獲得的差數，有更快的方法嗎？

我做錯了什麼？非常感謝您的幫助！

Answer 1

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

Answer 2

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 

?>

Answer 3

$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; 

這應該爲你工作。
