Are there alternative methods to using isset() for checking session variables in PHP?

When checking session variables in PHP, isset() is commonly used to determine if a variable is set and is not null. However, an alternative method to achieve the same result is by using the isset() function in combination with the empty() function. This can provide a more robust check for session variables as it also checks if the variable is empty. 

// Using isset() in combination with empty() to check session variables
if(isset($_SESSION['variable']) && !empty($_SESSION['variable'])) {
    // Variable is set and not empty
    // Perform necessary actions here
} else {
    // Variable is not set or empty
    // Handle accordingly
}
