How can the debugging process in PHP be optimized to identify and resolve issues related to password authentication and database queries?

Issue: To optimize the debugging process for password authentication and database queries in PHP, you can use error handling techniques such as try-catch blocks and outputting error messages to help identify and resolve issues more efficiently. 

// Example code snippet for password authentication with error handling
try {
    // Check if password matches hashed password in database
    if (password_verify($input_password, $hashed_password)) {
        // Password authentication successful
        echo "Password authentication successful";
    } else {
        // Password authentication failed
        throw new Exception("Password authentication failed");
    }
} catch (Exception $e) {
    // Output error message
    echo "Error: " . $e->getMessage();
}

// Example code snippet for database query with error handling
try {
    // Execute database query
    $result = $pdo->query("SELECT * FROM users");
    // Process query result
    foreach ($result as $row) {
        // Output data
        echo $row['username'] . "<br>";
    }
} catch (PDOException $e) {
    // Output error message
    echo "Database query error: " . $e->getMessage();
}
