What are the potential pitfalls of passing large amounts of data in a URL in PHP?

Passing large amounts of data in a URL in PHP can lead to security vulnerabilities as the data is visible in the browser's address bar and can be easily tampered with. To solve this issue, it is recommended to use POST requests to send large amounts of data securely without exposing it in the URL. 

```php
// Example of sending data using POST request in PHP
<form action="process_data.php" method="post">
    <input type="text" name="data1">
    <input type="text" name="data2">
    <input type="submit" value="Submit">
</form>
```
In the above code snippet, the data is sent using a POST request to a PHP script called `process_data.php`. This way, the data is not visible in the URL and is sent securely to the server.
