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

When naming variables in PHP scripts, it is important to use descriptive names that clearly indicate the purpose of the variable. Avoid using generic names like $temp or $data, as they can be confusing and make the code harder to read and maintain. Instead, use meaningful names that reflect the data or functionality the variable represents. Additionally, follow a consistent naming convention, such as camelCase or snake_case, to improve readability and make the code more organized. 

// Bad variable naming
$temp = 10;
$data = ["apple", "banana", "orange"];

// Good variable naming
$temperature = 10;
$fruits = ["apple", "banana", "orange"];
