How can the create_token function be modified to return the generated token instead of leaving the variable empty?

The issue can be solved by modifying the create_token function to return the generated token instead of leaving the variable empty. This can be achieved by assigning the generated token to a variable within the function and then returning that variable at the end of the function. This way, the function will generate a token and return it for further use.

function create_token() {
    $token = bin2hex(random_bytes(16));
    return $token;
}

$generated_token = create_token();
echo $generated_token;
