How can one generate a random output of multiple data sets from an array in PHP without any duplicates?

To generate a random output of multiple data sets from an array without any duplicates in PHP, you can shuffle the array and then select a subset of unique elements. One way to achieve this is to shuffle the array using the `shuffle()` function and then use the `array_slice()` function to select a subset of unique elements without duplicates. 

// Original array with data sets
$dataSets = ['A', 'B', 'C', 'D', 'E'];

// Shuffle the array
shuffle($dataSets);

// Select a subset of unique elements without duplicates
$randomDataSets = array_slice(array_unique($dataSets), 0, 3);

// Output the random data sets
print_r($randomDataSets);
