100铜币=1银 100银=1金

想写个根据多少铜币 返回相应等级的钱
比如参数为102135铜币 那就是返回10金21银35铜
比如参数为1544铜币 那就是返回15银44铜
以此类推...

php基础不扎实 不知道怎么写最精简

//简单点的

简单做。从额数最大的金开始处理,先整除,再模除,金银铜依次处理。输出的时候判断再做个判断,代码如下:

<code><?php function level($money){
        $gold   = floor($money / 10000);
        $money  = $money % 10000;

        $sliver = floor($money / 100);
        $cu     = $money % 100;

        $result = "";
        if($gold > 0) {
            $result .= $gold ."金";
        }
        if($sliver > 0) {
            $result .= $sliver ."银";    
        }
        if($cu > 0) {
            $result .= $cu ."铜";    
        }

        return $result;
    }

    //test
    echo level(102135);
    echo "<hr>";
    echo level(1544);
    echo "<hr>";
    echo level(99);

<code>function level($money){
    $ag = floor($money /100);
    $cu = $money % 100;
    $golden = floor($ag / 100);
    $ag =   $ag % 100;
    echo "{$golden}金{$ag}银{$cu}铜币";
}</code>

很简单的写了一个。

<code class="ruby">def make_change(money, coins)
  dp = [0]
  path = []
  result = {}

  coins.each_with_index do |coin, index|
    coin.upto(money) do |i|
      if !dp[i - coin].nil? && (dp[i].nil? || dp[i - coin] + 1  {1=>35, 100=>21, 10000=>10}</code>

嗯...不知道计算速度快 还是字符串截取速度快

<code><?php $money = 102135;
convert_money($money);

function convert_money($money) {
    $money = (string)$money;
    $coppers = substr($money,-2) ? substr($money,-2) : 0;
    $silver = substr($money,-4,-2) ? substr($money,-4,-2) : 0;
    $glod = substr($money,0,-4) ? substr($money,0,-4) : 0;

    echo "{$glod}金币{$silver}铜币{$coppers}银币";
}
</code></code>

结果: 10金币21铜币35银币

function change($number){

<code>    static $jin;
    static $yin;
    static $ton;
    if($number >= pow(10,4)){
        $jin = intval($number/pow(10,4));
        change($number -$jin*pow(10,4));
    }else if($number >= pow(10,2)){
        $yin = intval($number/pow(10,2));
        change($number-$yin*pow(10,2));
    }else{
        $ton = $number;
    }

    return array($jin,$yin,$ton);
}

$number = 10110245;
print_r(change($number));</code>

    $yin   = intval($coins/100 - $jin*100);
