Finding Unique Values Between Flat Arrays

Given two arrays, the task is to determine the values that exist only in one of them. This operation is commonly known as finding the difference between two sets.

In PHP, you can utilize the array_merge, array_diff, and array_diff functions to achieve this. Here's a detailed solution:

$array1 = [64, 98, 112, 92, 92, 92];
$array2 = [3, 26, 38, 40, 44, 46, 48, 52, 64, 68, 70, 72, 102, 104, 106, 92, 94, 96, 98, 100, 108, 110, 112];

// Calculate the difference between the two arrays
$diff1 = array_diff($array1, $array2);
$diff2 = array_diff($array2, $array1);

// Merge the two difference arrays to obtain the unique values
$fullDiff = array_merge($diff1, $diff2);

print_r($fullDiff);

This approach ensures that values present in both arrays are eliminated from the final result, leaving you with an array containing only the unique values that exist in one of the two original arrays.
