What are the potential pitfalls of not using proper error handling techniques in PHP scripts, as seen in the example provided?

Without proper error handling techniques in PHP scripts, errors or exceptions can go unnoticed, leading to unexpected behavior or security vulnerabilities. It is important to use functions like `try`, `catch`, and `finally` to handle exceptions and errors gracefully, providing informative error messages to users or logging them for debugging purposes. 

try {
    // Code that may throw an exception or error
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
} finally {
    // Optional cleanup code
}
