我需要编写一个 PHP 脚本来计算除以数字和提醒的时间数。可以说$amount=9200;，如果我将其除以5000 ，那么输出应该是5000: 1 timesand Reminder: 4200。我想我需要使用$n=$amount%5000;但我只有提醒而不是否。它分裂的次数。

谢谢！！

这就是众所周知的欧几里得划分： http ://en.wikipedia.org/wiki/Euclidean_division

$amount = 9200;
$divide = 5000;
$times = floor($amount/$divide);
$reminder = $amount%$divide;

echo "$amount = $times times $divide plus $reminder";

%操作员会给你余数，然后你需要做另一个操作来得到你划分的次数。

$times = floor($amount/5000);

$times = floor($amount / 5000);
$remainder = $amount % 5000;

<?php

class  ATM
{
    public function deliver( $note )
    {
        // code to grab that not from the cash boxes...
    }
}

$notes = new SplFixedArray(5);
$notes[0] = 100;
$notes[1] = 50;
$notes[2] = 20;
$notes[3] = 10;
$notes[4] = 5;

$notesKey = 0;

$withdraw = 920;
$allocated = 0;

$deliver = new SplQueue();

// work out biggest notes for remaining value and queue
while($allocated < $withdraw)
{
    $remains  = ($withdraw-$allocated) % $notes[$notesKey];
    $numNotes = (($withdraw-$allocated)-$remains)/$notes[$notesKey];
    for( $i = 0; $i < $numNotes; $i++ )
    {
        $allocated += $notes[$notesKey];
        $deliver->enqueue($notesKey);
    }
    ++$notesKey;
}

$atm = new ATM();
while(!$deliver->isempty())
{
     $atm->deliver($notes[$deliver->dequeue()]);
}
?>

像这样的东西应该可以解决问题......
