How can you use an array that represents a position for another array in PHP?

When using an array to represent a position for another array in PHP, you can access the specific index of the position array to retrieve the corresponding element from the other array. This allows you to easily associate elements between two arrays based on their positions. 

// Array representing positions
$positions = [0, 2, 1];

// Array with elements
$elements = ['apple', 'banana', 'cherry'];

// Access elements based on positions
foreach ($positions as $position) {
    echo $elements[$position] . "\n";
}
