PHP integer part padding

Question

I need to pad the integer part with 0, the integer part must be at least 2 characters

str_pad( 2    ,2,\"0\",STR_PAD_LEFT);// 02 -> works
str_pad( 22   ,2         


        

Answer 1

No, there is no simple way.

function padIntegerPart($n, $len) {
    $intPart = (int)$n;

    return str_repeat('0', max(0, $len - 1 - floor(log($intPart, 10)))) . $n;
}
