What are some best practices for naming variables in PHP to maintain code readability?

When naming variables in PHP, it is important to use descriptive names that clearly convey the purpose of the variable. Avoid using overly generic names like $data or $temp, as they do not provide any context to the reader. Instead, opt for names that accurately describe the data being stored, such as $username or $totalPrice. Additionally, follow a consistent naming convention, such as camelCase or snake_case, to improve code readability. 

// Example of using descriptive variable names in PHP
$userName = "JohnDoe";
$totalPrice = 100.50;

// Avoid using generic variable names
$data = ["apple", "banana", "orange"];
$temp = 25;

// Use consistent naming convention
$user_name = "JaneSmith";
$total_price = 75.25;
