PHP 來自數組的有序列表

Question

嗨，我正在嘗試從數組中打印出有序列表。 這是我現在的代碼：

    <?php


    $Salespeople = array(
    "Hiroshi Morinaga"=>57,
    "Judith Stein"=>44,
    "Jose Martinez"=>26,
    "Tyrone Winters"=>22,
    "Raja Singh"=>21);

    foreach ($Salespeople as $Salesperson) {
        echo key($Salespeople) . ": $Salesperson cars<br />";
        next($Salespeople);
    }
    ?>

我的問題是結果是這樣的：

    Judith Stein: 57 cars
    Jose Martinez: 44 cars
    Tyrone Winters: 26 cars
    Raja Singh: 22 cars
    : 21 cars

我怎樣才能使它顯示所有名稱，而不是像這樣打印出來？

    Hiroshi Morinaga: 57
    Judith Stein: 44 cars
    Jose Martinez: 26 cars
    Tyrone Winter: 22 cars
    Raja Singh: 21 cars

謝謝你。

Answer 1

想要這樣的東西嗎？

foreach($Salespeople as $fullname => $cars) 
{
    echo $fullname . ": " . $cars . " cars<br />";
}

Answer 2

使用 foreach 更簡單：

foreach ($Salespeople as $Salesperson => $Cars) {
    echo $Salesperson . ": $Cars cars<br />";
}

Answer 3

foreach將遍歷列表本身 - 您不需要使用key或next 。

foreach ($Salespeople as $name => $number) {
    echo $name . ": $number cars<br />";
}

Answer 4

只是為了好玩，您還可以使用array_map ：

 function echoSalesperson($v) { 
  echo $v . ": $Salesperson cars<br />" 
 }

 array_map($Salespeople,'echoSalesperson');
