What are the best practices for naming variables and arrays in PHP to ensure clarity and maintainability?

When naming variables and arrays in PHP, it is important to use descriptive names that clearly convey the purpose of the variable or array. This helps improve code readability and maintainability. It is recommended to use camelCase for variable names and snake_case for array names to follow PHP naming conventions. Avoid using abbreviations or overly generic names that may be confusing to other developers. 

// Good variable naming example
$userName = "JohnDoe";

// Good array naming example
$user_info = array(
    "name" => "John Doe",
    "age" => 30,
    "email" => "johndoe@example.com"
);
