In what ways can PHP developers ensure that their scripts are future-proof and maintain compatibility with upcoming PHP versions?

To ensure that PHP scripts are future-proof and maintain compatibility with upcoming PHP versions, developers can follow best practices such as using the latest PHP features responsibly, avoiding deprecated functions, and regularly updating their codebase to adhere to new PHP standards. 

// Example code snippet demonstrating the use of the null coalescing operator (??) to ensure compatibility with PHP 7.0 and later versions

// Before PHP 7.0
$var = isset($_GET['var']) ? $_GET['var'] : 'default';

// With null coalescing operator (PHP 7.0 and later)
$var = $_GET['var'] ?? 'default';
