Are there any potential issues with passing form variables in a URL in PHP, such as URL length limitations?

Passing form variables in a URL in PHP can lead to potential issues such as URL length limitations, security vulnerabilities, and exposing sensitive data. To solve this issue, it is recommended to use the POST method to submit form data instead of passing it in the URL. 

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