What is the best practice for checking boolean return values from PHP functions?

When checking boolean return values from PHP functions, it is best practice to use strict comparison operators (=== or !==) to ensure that the return value is exactly true or false. This helps prevent unexpected behavior due to type coercion. Additionally, you can use if statements to handle the true and false cases separately for better readability and maintainability. 

// Example of checking boolean return value with strict comparison
$result = someFunction();
if ($result === true) {
    // Handle true case
} elseif ($result === false) {
    // Handle false case
} else {
    // Handle other cases
}
