What are the best practices for naming variables and objects in PHP to ensure clarity and functionality?

When naming variables and objects in PHP, it is important to use descriptive and meaningful names that clearly convey their purpose and functionality. Avoid using vague or ambiguous 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. 

// Good practice: using descriptive names and camelCase convention
$firstName = "John";
$lastName = "Doe";

$userAge = 30;

// Bad practice: using vague names and inconsistent conventions
$fn = "John";
$ln = "Doe";

$age = 30;
