What are the limitations of manipulating URLs to display specific parameters in PHP applications?

When manipulating URLs to display specific parameters in PHP applications, one limitation is that it can make the code less secure as it exposes sensitive information in the URL. To solve this issue, it is recommended to use POST requests instead of GET requests when passing sensitive data. 

```php
<form method="post" action="process.php">
    <input type="hidden" name="username" value="john_doe">
    <input type="submit" value="Submit">
</form>
```

In the `process.php` file, you can access the username parameter using `$_POST['username']` instead of manipulating the URL directly.
