  URL:
  `page.php?name=Alex`
  
  ```php
  echo $_GET['name'];
  ```
  
  ## $_POST example
  
  HTML form:
  
  ```html
  <form method="post">
    <input name="email">
    <button>Send</button>
  </form>
  ```
  
  PHP:
  
  ```php
  if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    echo $_POST['email'];
