How can PHP developers ensure code portability and compatibility across different server environments, considering the issues faced in the forum thread?

Issue: PHP developers can ensure code portability and compatibility across different server environments by avoiding server-specific functions, using standard PHP functions, and checking for PHP version compatibility before executing code. Code snippet: 

// Check PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0') >= 0) {
    // Use standard PHP functions
    $result = json_encode($data);
} else {
    // Fallback for older PHP versions
    $result = json_encode($data, JSON_UNESCAPED_UNICODE);
}

echo $result;
