In what scenarios would it be recommended to use the POST method over the GET method when passing form data in PHP, considering security and data visibility concerns?

When passing sensitive information such as passwords or personal details through a form in PHP, it is recommended to use the POST method over the GET method. This is because data sent via POST is not visible in the URL, providing an added layer of security. Additionally, POST requests are not cached by browsers, further protecting the data from being stored in browser history or server logs. 

<form method="post" action="process_form.php">
  <label for="username">Username:</label>
  <input type="text" id="username" name="username">
  
  <label for="password">Password:</label>
  <input type="password" id="password" name="password">
  
  <input type="submit" value="Submit">
</form>
