How does the reset() function in PHP help in manipulating arrays for multiple outputs?

When manipulating arrays for multiple outputs in PHP, the reset() function can be used to reset the internal pointer of the array back to the first element. This is useful when iterating through an array multiple times or when needing to start the iteration from the beginning again. By using reset(), you can ensure that you are always starting from the first element of the array. 

// Example of using reset() function to manipulate arrays for multiple outputs
$array = [1, 2, 3, 4, 5];

// Output array elements twice
for ($i = 0; $i < 2; $i++) {
    reset($array);
    while ($element = current($array)) {
        echo $element . " ";
        next($array);
    }
    echo "\n";
}
