Description
$this -> session -> userdata return wrong result when the session value is set to 0
PS: please excuse my poor english
Code Sample
I tried to use something like this:
if ($this -> session -> userdata('filter_status')) {
$this -> db -> where('enabled', $this -> session -> userdata('filter_status'), false);
}
Expected Result
$this -> session -> userdata(‘key’) should be 0, as an integer
Actual Result
$this -> session -> userdata(‘key’) return 0 as FALSE

This isn’t a bug, it’s expected PHP behaviour. Integer 0 evaluates to false when implicitly cast to boolean. To check for true boolean false use the !== operator. e.g. if ($this->session->userdata(‘filter_status’) !== false) { |
