ok,i've solved the problem myself , look here:

function scot($nr)
{
$rez=0;
while($nr>20)
{
$rez=$nr%10+$rez*10;
$nr=$nr/10;
$nr=floor($nr);
};
return $rez;
};

function inv($nr)
{
$rez=0;
while($nr>0)
{
$rez=$nr%10+$rez*10;
$nr=$nr/10;
$nr=floor($nr);
};
return $rez;
};
print(inv(scot(201234567)));

returns 1234567;
