I saw this question here in Stack Overflow How to round to the nearest ten? and found it very interesting.
Only the question is about JavaScript.
How could I round off a number to the nearest ten in PHP?
Example:
11 => 20
23 => 30,
2.5 => 10

Would you like to leave numbers from 0 always in tens? If yes, see if this example helps:
$num = 11;
$num = ceil($num / 10) * 10;

What I use here is:
function roundByValue($valor, $valorArredondamento){
if($valorArredondamento != 0){
$valor = round($valor/$valorArredondamento)*$valorArredondamento;
}
return $valor;
}
// pr = print_r
pr(roundByValue(10.5, 1)); // 11
pr(roundByValue(10.23, 0.5)); // 10
pr(roundByValue(10.27, 0.5)); // 10.5
pr(roundByValue(10.07, 0.25)); // 10
pr(roundByValue(10.74, 0.10)); // 10.7
pr(roundByValue(10.17, 0.75)); // 10.5
