What are the best practices for naming variables and arrays in PHP to avoid confusion?

When naming variables and arrays in PHP, it is important to use descriptive names that clearly indicate their purpose or content. Avoid using ambiguous or generic names that could lead to confusion. Additionally, follow a consistent naming convention such as camelCase or snake_case to make your code more readable and maintainable. 

// Bad practice - ambiguous variable names
$var = "Hello";
$arr = [1, 2, 3];

// Good practice - descriptive variable names
$message = "Hello";
$numbers = [1, 2, 3];
