In PHP, what are the best practices for maintaining readability and understanding when assigning boolean values based on comparison operators, as demonstrated in the code snippet?

When assigning boolean values based on comparison operators in PHP, it is important to maintain readability and understanding for future developers. One way to achieve this is by using explicit boolean values (true or false) instead of relying on the truthiness of the comparison result. This makes the code more clear and less error-prone.

// Example of maintaining readability and understanding when assigning boolean values based on comparison operators
$age = 25;
$isAdult = ($age >= 18) ? true : false;

// Using explicit boolean values for better readability
$isAdult = ($age >= 18) ? true : false;
