What is the correct way to output the results of array_unique() in PHP to avoid errors?

When using the array_unique() function in PHP to remove duplicate values from an array, it is important to remember that the function returns a new array with unique values. To output the results correctly and avoid errors, you should use a loop to iterate over the unique array and print each value separately.

// Sample array with duplicate values
$array = [1, 2, 2, 3, 4, 4, 5];

// Get unique values from the array
$uniqueArray = array_unique($array);

// Output the unique values using a loop
foreach ($uniqueArray as $value) {
    echo $value . "\n";
}
