How can the issue of the script not functioning properly be resolved when using array_unique()?

When using array_unique(), the issue of the script not functioning properly can be resolved by ensuring that the array values are of the same type. If the values are of different types, array_unique() may not work as expected. To resolve this, you can use array_map() with the strval() function to convert all values to strings before applying array_unique(). 

// Convert array values to strings before using array_unique()
$array = [1, '1', 2, '2', 3, '3'];
$array = array_map('strval', $array);
$array = array_unique($array);

print_r($array);
