php complex numbering computing

I have an orderId which obviously is variable.

I need to compute another 9 digit number based on that.

Example:

$orderId = 100;

$path should be = 0000000100;

----
$orderId = 2350;

$path should be = 0000002000;


--- 
$orderId = 7500;

$path should be = 0000007000;

Thanks a lot in advance!

Try like this 

 <?php
  $test = strval(7001);
  echo substr_replace(str_pad("",9,"0"),$test[0],(strlen($test)-1)*(-1),0);
?>

Another way is 

<?php
$test = 658;
$length = 10-strlen($test);
$str_pad = "0000000000";
$str_pad[$length] = strval($test)[0];
echo $final = $str_pad
?>
