What is the best method to handle form submissions in PHP to avoid overriding URL parameters?

When handling form submissions in PHP, it is important to ensure that URL parameters are not overridden during the form submission process. One way to avoid this issue is to use the POST method for form submissions instead of the GET method. By using POST, the form data is sent in the request body rather than in the URL, which helps to prevent any conflicts with existing URL parameters. 

<form method="post" action="process_form.php">
  <!-- form fields go here -->
  <input type="submit" value="Submit">
</form>
```

In the process_form.php file:

```php
<?php
  // Handle form submission
  if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
  }
?>
