Get a session variable
- This method returns the value of the requested session variable, or NULL if it's not present.
- You can optionally use a namespace with this method, to avoid collisions with other session variables. But if using namespaces we recommended using the dedicated getFor() and setFor() methods instead.
- You can also get or set non-namespaced session values directly (see examples).
Examples
// Set value "Bob" to session variable named "firstName"
$session->set('firstName', 'Bob');
// You can retrieve the firstName now, or any later request
$firstName = $session->get('firstName');
// outputs: Hello Bob
echo "Hello $firstName"; // Setting and getting a session value directly
$session->firstName = 'Bob';
$firstName = $session->firstName;Usage
// basic usage
$mixed = $session->get($key);
// usage with all arguments
$mixed = $session->get($key, string $_key = null);Arguments
| Name | Type(s) | Description |
