$session->set() method

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

NameType(s)Description
keystring, object

Name of session variable to set (or object for namespace)

valuestring, 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

$this

Object instance it was called from (method supports fluent interface).
