What are some best practices for naming variables and objects in PHP to avoid confusion and errors?

When naming variables and objects in PHP, it is important to use descriptive names that clearly convey the purpose or content of the variable. Avoid using abbreviations or overly generic names that could lead to confusion or errors in your code. Additionally, follow a consistent naming convention, such as camelCase or snake_case, to make your code more readable and maintainable.

// Bad example
$var = 10;
$myObj = new MyClass();

// Good example
$counter = 10;
$userProfile = new UserProfile();
