Getting value from form in php

Getting value from form in php

I have a question about php: how do I get the value values from input from form, if form has not been sent yet, how do I do this? Or tell me how to do it so that when you click on input in php, only the value of input is sent? And also, if possible, how do I get the data in the same file without sending it to another one?

In this code, the $message variable is created and the input value is entered into it. If you want to save the value of a variable after opening the page again, you can create a session (use a cookie).

<!DOCTYPE html>
<html lang="ru">
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>
  <form action="" method="post">
    <input type="text" name="message" />
    <input type="submit" name="send" value="Отправить" />
  </form>
  <?php
    if(isset($_POST["message"])){$message = $_POST["message"]; echo $message;}
  ?>
  </body>
</html>
