What potential pitfalls should be considered when using the GET method to transfer data to a web server in PHP?

One potential pitfall of using the GET method to transfer data to a web server in PHP is that sensitive information, such as passwords or personal data, can be exposed in the URL. To mitigate this risk, sensitive data should be transmitted using the POST method instead. Additionally, using the GET method for large amounts of data can lead to URL length limitations and potential security vulnerabilities. 

<form method="post" action="process_data.php">
  <input type="text" name="username" placeholder="Username">
  <input type="password" name="password" placeholder="Password">
  <button type="submit">Submit</button>
</form>
