从PHP中最后一次运行do while循环时删除echo命令

我通过codeacademy学习PHP。我已经完成了第一个do while循环（）

我有一句话不合逻辑。如何删除该行：

“图书馆仍然开放。”

仅从循环的最后一次运行（6点钟）开始

---

在那里粘贴一点if语句，看看它们是否匹配（如果不是关闭时间），然后瞧

<?php

$closingtime = 6;
$time = 2;
do {
    echo "<div class=\"coin\">{$time}</div>";
    echo "The current time is {$time}.";
    if($closingtime != $time)
        echo "<p>The library is still open.</p>";
    $time ++;
}
while ($time <= $closingtime);
echo "<p>The library is closed.</p>";


echo "<p>The library closes at <div class=\"coin\">{$closingtime}</div>";

?>

这样，如果$closingtime和$time不相同，应用程序将只回显“库仍然打开”。因此，当它们相同时，它不会显示该语句

<?php

$closingtime = 6;
$time = 2;
do {
    echo "<div class=\"coin\">{$time}</div>";
    echo "The current time is {$time}.";
    if($closingtime != $time)
        echo "<p>The library is still open.</p>";
    $time ++;
}
while ($time <= $closingtime);
echo "<p>The library is closed.</p>";


echo "<p>The library closes at <div class=\"coin\">{$closingtime}</div>";

?>
