How can developers ensure code portability and compatibility across different PHP environments?

Developers can ensure code portability and compatibility across different PHP environments by following best practices such as using PHP version compatibility checks, avoiding deprecated functions, and utilizing cross-platform libraries and frameworks. Additionally, using PHP configuration files to set environment-specific variables can help streamline deployment processes. 

// Check PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    die('This code requires at least PHP version 7.0.0');
}

// Avoid deprecated functions
if (!function_exists('deprecated_function')) {
    function deprecated_function() {
        // Function implementation
    }
}

// Use environment-specific variables
$config = include 'config.' . $_SERVER['ENVIRONMENT'] . '.php';
