Can you explain the concept of expressions returning boolean values in PHP and how they can be directly assigned to variables?

In PHP, expressions can return boolean values, which are either true or false. These boolean values can be directly assigned to variables for further use in conditional statements or other logic. This allows for efficient and concise coding practices. 

// Example of assigning a boolean expression directly to a variable
$isTrue = (5 > 3); // $isTrue will now hold the value true
$isFalse = (2 == '2'); // $isFalse will now hold the value false
