$number = ceil($input * 0.1)/0.1 ;
Hey i modify Kenny answer and custom it not always round function now it can be ceil and floor function

function roundToTheNearestAnything($value, $roundTo,$type='round')
    {
        $mod = $value%$roundTo;
        if($type=='round'){
            return $value+($mod<($roundTo/2)?-$mod:$roundTo-$mod);
        }elseif($type=='floor'){
            return $value+($mod<($roundTo/2)?-$mod:-$mod);
        }elseif($type=='ceil'){
            return $value+($mod<($roundTo/2)?$roundTo-$mod:$roundTo-$mod);
        }

    }

echo roundToTheNearestAnything(1872,25,'floor'); // 1850<br>
echo roundToTheNearestAnything(1872,25,'ceil'); // 1875<br>
echo roundToTheNearestAnything(1872,25,'round'); // 1875

This can be easily accomplished using PHP 'fmod' function. The code below is specific to 10 but you can change it to any number.

$num=97;
$r=fmod($num,10);
$r=10-$r;
$r=$num+$r;
return $r;

OUTPUT: 100
