|
|
* Start new or resume existing session. |
|
21
|
|
|
* |
|
22
|
|
|
* @param string $name [optional] The session name references the name of the |
|
23
|
|
|
* session, which is used in cookies and URLs (e.g. PHPSESSID). |
|
24
|
|
|
* It should contain only alphanumeric characters; it should be short |
|
25
|
|
|
* and descriptive (i.e. for users with enabled cookie warnings). |
|
26
|
|
|
* If name is specified, the name of the current session is changed |
|
27
|
|
|
* to its value. |
|
28
|
|
|
* |
|
29
|
|
|
* The session name can't consist of digits only, at least one letter |
|
30
|
|
|
* must be present. Otherwise a new session id is generated every time. |
|
31
|
|
|
* @param array $iniSettings [optional] List of parameters for the ini_set() function. |
|
32
|
|
|
* |
|
33
|
|
|
* @param bool $useCookie [optional] Use cookie or not. All next arguments |
|
34
|
|
|
* works only if this parameter is TRUE. |
|
35
|
|
|
* @param int $lifetime [optional] Lifetime of the session cookie, defined in seconds. |
|
36
|
|
|
* @param string $path [optional] Path on the domain where the cookie will work. |
|
37
|
|
|
* Use a single slash ('/') for all paths on the domain. |
|
38
|
|
|
* @param string $domain [optional] Cookie domain, for example 'www.asymptix.com'. |
|
39
|
|
|
* To make cookies visible on all subdomains then the domain must |
|
40
|
|
|
* be prefixed with a dot like '.asymptix.com'. |
|
41
|
|
|
* @param bool $secure [optional] If TRUE cookie will only be sent over secure connections. |
|
42
|
|
|
* @param bool $httponly [optional] If set to TRUE then PHP will attempt to |
|
43
|
|
|
* send the httponly flag when setting the session cookie. |
|
44
|
|
|
* |
|
45
|
|
|
* @return mixed This function returns TRUE if a session was successfully |
|
46
|
|
|
* started, otherwise FALSE. If session was resumed returns session |
|
47
|
|
|
* status: PHP_SESSION_DISABLED if sessions are disabled. |
|
48
|
|
|
* PHP_SESSION_NONE if sessions are enabled, but none exists. |
|
49
|
|

* PHP_SESSION_ACTIVE if sessions are enabled, and one exists. |

Instead of super-globals, we recommend to explicitly inject the dependencies of your class. This makes your code less dependent on global state and it becomes generally more testable:
