How does the use of foreach and range functions in PHP simplify the process of generating unique random numbers?

When generating unique random numbers in PHP, one common issue is ensuring that each number is unique within a given range. Using a combination of the foreach loop and the range function can simplify this process. By creating an array with a range of numbers, shuffling it, and then iterating over it with a foreach loop, we can easily generate unique random numbers without duplicates.

// Generate unique random numbers within a specified range
$min = 1;
$max = 10;
$numbers = range($min, $max);
shuffle($numbers);

foreach ($numbers as $number) {
    echo $number . " ";
}
