What are some best practices for naming variables and database columns in PHP to avoid confusion and improve readability?

When naming variables and database columns in PHP, it is important to use descriptive and meaningful names that accurately represent the data they hold. Avoid using abbreviations or overly generic names that could lead to confusion. Additionally, follow a consistent naming convention, such as camelCase or snake_case, to improve readability and maintainability of your code. 

// Example of naming variables using camelCase
$userName = "JohnDoe";
$userAge = 30;

// Example of naming database columns using snake_case
$query = "SELECT first_name, last_name, email FROM users";
