Set a session variable
- 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
$session->set($key, $value);
// usage with all arguments
$session->set($key, $value, mixed $_value = null);Arguments
| Name | Type(s) | Description |
|---|---|---|
key | string, object | Name of session variable to set (or object for namespace) |
value | string, mixed | Value to set (or name of variable, if first argument is namespace) |
_value (optional) | mixed | Value to set if first argument is namespace. Omit otherwise. |
Return value
$thisObject instance it was called from (method supports fluent interface).
