将浮点数分成数组

So I have a decimal (5,2) that I am trying to separate into an array.

So if the number is..

123.45 = array([0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )

23.45 = array([0] => 0 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )

3.45 = array([0] => 0 [1] => 0 [2] => 3 [3] => 4 [4] => 5 )

I have a pretty large code to do this, and I wanted to know if anyone had a simpler way of putting each digit into this array because I feel like mine is pretty convoluted.

$number = 123.35;
$number_array = explode(".", $number);
$final_array = array(0);

if(!empty(@(string)$number_array[0][0]) && !empty(@(string)$number_array[0][1]) && !empty(@(string)$number_array[0][2]))
{
    $final_array[0] = @(string)$number_array[0][0];
    $final_array[1] = @(string)$number_array[0][1];
    $final_array[2] = @(string)$number_array[0][2];
}
elseif(!empty(@(string)$number_array[0][0]) && !empty(@(string)$number_array[0][1]) && empty(@(string)$number_array[0][2]))
{
    $final_array[0] = 0;
    $final_array[1] = @(string)$number_array[0][0];
    $final_array[2] = @(string)$number_array[0][1];
}
elseif(!empty(@(string)$number_array[0][0]) && empty(@(string)$number_array[0][1]) && empty(@(string)$number_array[0][2]))
{
    $final_array[0] = 0;
    $final_array[1] = 0;
    $final_array[2] = @(string)$number_array[0][0];
}
else
{
    $final_array[0] = 0;
    $final_array[1] = 0;
    $final_array[2] = 0;
}

empty(@(string)$number_array[1][0]) ? $final_array[3] = 0 : $final_array[3] = @(string)$number_array[1][0];
empty(@(string)$number_array[1][1]) ? $final_array[4] = 0 : $final_array[4] = @(string)$number_array[1][1];

    $number = str_replace('.', '', (string) 13.35);
    $number = str_pad($number, 5, "0", STR_PAD_LEFT);
    var_dump(str_split($number));
