How can PHP be used to generate random numbers without repetition?

When generating random numbers in PHP without repetition, one approach is to create an array containing all possible numbers, shuffle the array, and then iterate through it to get unique random numbers. This ensures that each number is picked only once. 

// Create an array of numbers
$numbers = range(1, 10);

// Shuffle the array
shuffle($numbers);

// Iterate through the shuffled array to get unique random numbers
foreach ($numbers as $number) {
    echo $number . "\n";
}
