If it does not work on all integers to just devide by 10, it probably is because of rounding?
So...

$newint = floor($payerd_amount / 10);
// if the number is 123456, newint will be 12345

You can start from 0 replace with 1. Example

$payerd_amount = 20000000;
$payerd_amount = substr((string)$payerd_amount,0,strlen((string)$payerd_amount) -1);
print($payerd_amount);

Output

If all you want to do is remove the last zero, just divide by 10

   $payerd_amount = $payerd_amount / 10;

This works, too:

   $payerd_amount = substr($payerd_amount, 0, -1);

Try this:

$payerd_amount = substr($payerd_amount, 0, -1);
