What are some best practices for handling SQL errors in PHP?

When handling SQL errors in PHP, it is important to properly catch and handle these errors to prevent potential security vulnerabilities and improve the user experience. Some best practices include using try-catch blocks to catch exceptions thrown by SQL queries, logging errors for debugging purposes, and providing informative error messages to users. 

try {
    // SQL query that may throw an exception
    $result = $pdo->query("SELECT * FROM users");
} catch (PDOException $e) {
    // Log the error for debugging purposes
    error_log('SQL Error: ' . $e->getMessage());
    
    // Inform the user about the error
    echo 'An error occurred while processing your request. Please try again later.';
}
