How can PHP developers handle edge cases where the number of unique random numbers required exceeds the range of possible values?

When the number of unique random numbers required exceeds the range of possible values, PHP developers can implement a shuffling algorithm to generate a list of unique numbers within the desired range. This algorithm shuffles an array containing numbers within the range and then selects the required number of unique values from the shuffled array.

function generateUniqueRandomNumbers($min, $max, $count) {
    $numbers = range($min, $max);
    shuffle($numbers);
    return array_slice($numbers, 0, $count);
}

$min = 1;
$max = 100;
$count = 10;

$uniqueNumbers = generateUniqueRandomNumbers($min, $max, $count);
print_r($uniqueNumbers);
