Array compare

[sandy1028]

Hi,

Two arrays

array_1=array(A,B,C);
arry_2=array(A,A,B,B,A,B,A,😎;

How to find out the element which is not in arry_2.

Here in the above example the element should show as C.

Your code has some issues as is..
Your need to use dollarsigns infront of your array_1 and array_2 variables..
You need to use quotes for the values of the keys inside the arrays..otherwise, you get 'Notice: Use of undefined constant X'

Try:

$array_1 = array('A','B','C');
$array_2 = array('A','A','B','B','A','B','A','B');
$difference = array_diff($array_1, $array_2);
foreach($difference as $valDiff){
     echo $valDiff;
}
