Round to max thousand, hundred etc in PHP

Question

I have a pretty simple PHP question but I\'m not sure how to do that.

I want to round to the max hundred or thousand depending on the value returned by the database

Answer 1

Here is my 2 cents:

$v = 11;

if(strlen($v)<4) { 
    $v = str_pad((int)(substr($v, 0, 1)+1), strlen($v), 0, STR_PAD_RIGHT);
} else {
    $v = substr($v, 0, -4) . str_pad((int)(substr($v, -4, -3)+1), 4, 0, STR_PAD_RIGHT);
}
