What are the potential consequences of not handling errors properly in PHP scripts?

Improper error handling in PHP scripts can lead to security vulnerabilities, data leakage, and unexpected behavior for users. It is essential to handle errors gracefully by logging them, displaying user-friendly error messages, and avoiding exposing sensitive information to users.

// Example of proper error handling in PHP
try {
    // Code that may throw an exception
    throw new Exception("An error occurred");
} catch (Exception $e) {
    // Log the error
    error_log("Error: " . $e->getMessage());
    
    // Display a user-friendly error message
    echo "An error occurred. Please try again later.";
}
