How can I efficiently merge two arrays of email values while ensuring only unique emails remain?

Efficiently Combining Arrays with Unique Values

Combining multiple arrays while preserving unique values is a common task in programming. In this scenario, we're given two arrays of objects containing email values, and we need to merge them into a single array, ensuring that there are no duplicate emails.

To achieve this using PHP, we can leverage a combination of two functions:

1. array_merge(): This function combines multiple arrays into a single array.
2. array_unique(): This function removes duplicate values from an array.

To merge the two arrays and filter out duplicates, we can use the following code:

$array = array_unique(array_merge($array1, $array2));

The array_merge() function combines the two input arrays into a single array. The resulting array may contain duplicate email values.

The array_unique() function then takes the combined array and removes any duplicate values, returning an array with only unique emails.

Using this approach, we can efficiently merge the two arrays and ensure that there are no duplicate values in the final result. The expected output, as shown in the example provided, will be an array of objects with unique email values.
