Without having to call each session by name, is there a way to display the contents of all sessions currently set?
echo '<pre>'; var_dump($_SESSION); echo '</pre>';
Or you can use
print_r if you don't care about types. If you use
print_r, you can make the second argument
TRUE so it will return instead of echo, useful for...
echo '<pre>' . print_r($_SESSION, TRUE) . '</pre>';
