Appending format

[nintondo]

hi i need help in appending a format to a string

 

eg.

 

given

number : 123

desired outcome--->000/000/000/000/123 

number : 12345

desired outcome---> 000/000/000/012/345

 

meaning every 3 numbers @ the back is prepended with a '/'

 

how do I go about doing this?

function your_format($number){
$string = str_pad($number, 15, '0', STR_PAD_LEFT);
$array = str_split($string, 3);
$result = implode('/', $array);
return $result;
}
echo your_format(123);
echo "<br />";
echo your_format(12345);
