The ternary conditional operator in PHP is used as a shorthand for an if-else statement. It allows you to conditionally choose between two values based on a condition. The syntax is condition ? value_if_true : value_if_false;. If the condition evaluates to true, the value before the : is returned; otherwise, the value after the : is returned. For example, $message = $isLogged ? "Welcome back!" : "Please log in"; assigns the value "Welcome back!" to $message if $isLogged is true, and "Please log in" otherwise. The ternary conditional operator can be used to simplify code and make it more concise, especially when assigning values based on simple conditions. It's important to use the ternary conditional operator judiciously to maintain code readability and avoid excessive nesting or complex conditions.
