Question

我目前正在玩数组，这是我到目前为止所做的：

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>13.15</title>
  </head>
  <body>
      <form method="post">
         fruit: <input type="text" name="fruit"><br><br>
         <input type="submit" name="add" value="add"><br><br>
         -------------------------<br><br>
         <input type="submit" name="sort" value="sort"> <input type="submit" name="shuffle" value="'shuffle'"><br><br>
         -------------------------
         <br><br>
      </form>
<?php
$fruit = array("Apple", "Mango", "Pear", "Banana");

if(isset($_POST['sort']))
{
sort($fruit);
foreach ($fruit as $key => $val) {
    echo "- " .  $val . "<br />" . "\n";
}
}

if(isset($_POST['shuffle']))
{
shuffle($fruit);
foreach ($fruit as $key => $val) {
    echo "- " .  $val . "<br />" . "\n";
}
}

?>
</body>
</html>

将水果添加到阵列的最佳方法是什么？我已经为它创建了按钮和输入字段，但我似乎找不到最适合它的代码

按下按钮后添加到数组
