This is my code. Very simple, isn't it. But it doesn't work and I don't get it.. I always thought that PHP only executes when I load the page, but the other page where I use same code works very well without JS..
这是我的代码。很简单，不是吗。但它不起作用，我不明白..我一直认为PHP只在我加载页面时执行，但我使用相同代码的另一个页面在没有JS的情况下工作得很好..

You need to wrap your button in a <form>tag:
您需要将按钮包装在<form>标签中：
<form action="" method="post">
<input type="submit" name="submit" id="submit" class="button" value="Submit"/>
</form>

You need a form surrounding the input.
您需要一个围绕输入的表单。
<body>
<form action="welcome.php" method="post">
<input type="submit" name="submit" id="submit" class="button" value="Submit"/>
</form>
</body>
</html>

You have no form tag and even if you did it would need the method="post" attribute.
你没有表单标签，即使你做了它也需要 method="post" 属性。
<form method="post" action="<?php echo $_SERVER[PHP_SELF]?>">
<input type="submit" name="submit" id="submit" class="button" value="Submit"/>
</form>
