在PHP中舍入到最大千，百等

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.

Here are a few examples of what I need :

• DB returns the value 11, I want PHP to output 20
• DB returns the value 104, I want PHP to output 200
• DB returns the value 1404, I want PHP to output 2000
• DB returns the value 10241, I want PHP to output 11000

etc etc

I would like to create an automatic function to do that, according to the value passed.

Thanks!

Final implementation, inspired from Shaunkak's answer and SO's comment. Thanks for these bra..s. live demo

<?php
  $val = 10241.67;
  if($val >= 1000) {
    echo ceil($val / 1000) * 1000;
  }
  else {
    $length = strlen(ceil($val));
    $times = str_pad('1', $length, "0");
    echo ceil($val / $times) * $times;
}
