What is the best practice for selecting random elements from multiple arrays in PHP?

When selecting random elements from multiple arrays in PHP, one approach is to combine all the arrays into a single array and then use the `array_rand()` function to select random elements from the combined array. This ensures that each element has an equal chance of being selected. 

// Combine multiple arrays into a single array
$array1 = [1, 2, 3];
$array2 = ['a', 'b', 'c'];
$combinedArray = array_merge($array1, $array2);

// Select a random element from the combined array
$randomElement = $combinedArray[array_rand($combinedArray)];

echo $randomElement;
