Here is the translation:

function toFixed($number, $dec_length){
    $pos=strpos($number.'', ".");
    if($pos>0){
        $int_str=substr($number,0,$pos);
        $dec_str=substr($number, $pos+1);
        if(strlen($dec_str)>$dec_length){
            return $int_str.($dec_length>0?'.':'').substr($dec_str, 0,$dec_length);
        }else{
            return $number;
        }
    }else{
        return $number;
    }
}


//toFixed(1234.678, 0) = 1234
//toFixed(1234.678, 1) = 1234.6
//toFixed(1234.678, 2) = 1234.67
//toFixed(1234.678, 4) = 1234.678
