What are the potential security risks of passing sensitive data through URLs in PHP?

Passing sensitive data through URLs in PHP can pose security risks as the data can be easily accessed and viewed by unauthorized users. To mitigate this risk, sensitive data should be passed through POST requests instead of GET requests, as POST requests do not expose data in the URL. By using POST requests, sensitive information is sent in the request body, making it more secure. 

<form action="process_data.php" method="post">
  <input type="hidden" name="sensitive_data" value="your_sensitive_data_here">
  <input type="submit" value="Submit">
</form>
```
In the process_data.php file:
```php
<?php
  $sensitive_data = $_POST['sensitive_data'];
  // Process the sensitive data securely
?>
