剛開始學php
單純想要測試php post表單並顯示輸入值

<body> 
<?php
$User = "";
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
    if(isset($_POST["User"])) {
        $User = $_POST["User"];
    }
}
?>

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
    <input type="text" name="User"  />
    <input type="button" value="Submit">
</form>

<?php
echo "<h3>input</h3>";
echo $User;
echo "<br>";
?>
</body>

但是按鈕點下去都沒反應,不太清楚是按鈕沒讀取到還是讀取到但是沒動作

環境是用docker蓋的,不知道有沒有關係

version: '3' 
services: 
  nginx:
    image: nginx:stable-alpine
    ports:
      - "8083:80"
    volumes:
      - ./conf.d:/etc/nginx/conf.d 
      - ./php:/var/www/html
    links:
      - myphp-fpm:php
  myphp-fpm:
    image: php:rc-fpm-alpine3.12
    ports:
      - "9000:9000"
    volumes:
      - ./php:/var/www/html

查了一下php:rc-fpm-alpine3.12 應該是用php8.0
