What are the potential consequences of multiple spaces being replaced by a single space in PHP scripts?

When multiple spaces are replaced by a single space in PHP scripts, it can affect the formatting and readability of the code. This can make it harder for developers to understand and maintain the code. To solve this issue, you can use the `preg_replace` function in PHP to replace multiple spaces with a single space. 

// Replace multiple spaces with a single space
$code = preg_replace('/\s+/', ' ', $code);
