這個 form 的意思是當網友按下"送出表單"的按鈕時，將透過 post 的方法將 MyName 傳遞給 post.php 這支 PHP 程式。 備註：POST method 有資料量 8Mb 的限制，如果你要修改這個限制可以透過 php.ini 來設定。

当用户填写上面的表单并点击提交按钮时，表单数据将通过 HTTP POST 方法发送到名为 "welcome.php" 的 PHP 文件进行处理。 要显示提交的数据，您可以简单地输出所有变量。

When a user fills out the form above and clicks the submit button, the form data is sent for processing to a PHP file named "welcome.php". The form data is sent with the HTTP POST method.

When a user clicks the submit button, the form data is sent to the PHP file specified in the action attribute of the <form> tag. In the PHP file we can use the $_POST variable to collect the value of the input field.

In PHP, the $_POST variable is used to collect values from HTML forms using method post. Information sent from a form with the POST method is invisible and has no limits on the amount of information to send.
