What is the correct usage of array_rand() function in PHP for selecting random elements?

When using the array_rand() function in PHP to select random elements from an array, it is important to note that the function returns either a single key or an array of keys, not the actual values. To get the random elements themselves, you need to use the returned key(s) to access the corresponding values in the original array. Here is an example of how to correctly use array_rand() to select random elements from an array: 

$colors = array("red", "blue", "green", "yellow", "orange");
$random_keys = array_rand($colors, 2);

foreach($random_keys as $key){
    echo $colors[$key] . "\n";
}
