Are there any limitations or restrictions when passing multiple variables through a link in PHP?

When passing multiple variables through a link in PHP, there is a limitation on the length of the URL due to browser and server restrictions. To overcome this limitation, you can use the POST method instead of the GET method to send the variables through a form submission. This way, the variables are sent in the request body rather than the URL, allowing for larger amounts of data to be transferred. 

```php
<form action="process.php" method="post">
    <input type="hidden" name="variable1" value="value1">
    <input type="hidden" name="variable2" value="value2">
    <input type="submit" value="Submit">
</form>
```

In the above code snippet, the variables "variable1" and "variable2" are passed to the "process.php" script using the POST method. This allows for passing multiple variables without being limited by the URL length.
