What is the potential issue with using the GET method to pass a variable to a PHP file?

Using the GET method to pass variables to a PHP file can potentially expose sensitive information as the variables are visible in the URL. To solve this issue, you can use the POST method instead, which sends the data in the HTTP request body rather than in the URL. 

<form method="post" action="process.php">
    <input type="text" name="variable">
    <button type="submit">Submit</button>
</form>
```

In the "process.php" file, you can access the variable using $_POST:

```php
$variable = $_POST['variable'];
