<?php
function groupByOwners(array $files) : array

Created January 15, 2021 13:40
2. Merge Names Implement the unique_names function. When passed two arrays of names, it will return an array containing the names that appear in either or both arrays. The returned array should have no duplicates. For example, calling unique_names(['Ava', 'Emma', 'Olivia'], ['Olivia', 'Sophia', 'Emma']) should return ['Emma', 'Olivia', 'Ava', '…
<?php
function unique_names(array $array1, array $array2) : array
{
return array_unique(array_merge($array1, $array2));
}
$names = unique_names(['Ava', 'Emma', 'Olivia'], ['Olivia', 'Sophia', 'Emma']);
echo join(', ', $names); // should print Emma, Olivia, Ava, Sophia
