Application::getSession

Get SESSION data

Description

public mixed Application::getSession( string $name = '' )

Get SESSION data. If the key does not exist, returns ''. If you omit the argument, returns all SESSION data as an array.

getSession() does not create a session: when the request has no session cookie (and nothing was written to the session yet), it returns '' (or array() without an argument) and no cookie is sent. An existing session is opened to read it.

Arguments

Name	Data type	Default	Remarks
$name	string	''	Session key. All SESSION data when omitted

Example

Controller - First request

$this->setSession('foo', 'bar');

Controller - Second request

echo $this->getSession('foo'); // -> bar
echo $this->getSession('none'); // -> '' (empty string)

Get all session data

If you omit the argument, getSession returns all SESSION data.

Controller - First request

$this->setSession('foo', 'bar');
$this->setSession('baz', 'qux');

Controller - Second request

var_dump( $this->getSession() );

Output

array(2) { ["foo"]=> string(3) "bar" ["baz"]=> string(3) "qux" }
