“如何让用户使用$_POST在单个页面上添加两个随机整数”

<form method="POST" action="">
  <label for="num1">整数1：</label>
  <input type="number" name="num1" id="num1" required>
  <br>
  <label for="num2">整数2：</label>
  <input type="number" name="num2" id="num2" required>
  <br>
  <input type="submit" value="提交">
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $num1 = $_POST["num1"];
  $num2 = $_POST["num2"];

  // 进行处理，例如计算两个整数的和
  $sum = $num1 + $num2;

  echo "整数1：$num1<br>";
  echo "整数2：$num2<br>";
  echo "和：$sum";
}
?>
