How can differences in server configurations between local and remote environments affect PHP code execution?

Differences in server configurations between local and remote environments can affect PHP code execution by causing discrepancies in settings such as PHP version, extensions, and server variables. To ensure consistent behavior, it's important to use environment-specific configuration files and settings. Additionally, using tools like Docker or Vagrant can help create identical development and production environments. 

// Example of using environment-specific configuration files
if (file_exists('config.local.php')) {
    include 'config.local.php';
} else {
    include 'config.php';
}
