session_encode — Encodes the current session data as a session encoded string
session_encode() returns a serialized string of the contents of the current session data stored in the $_SESSION superglobal.
By default, the serialization method used is internal to PHP, and is not the same as serialize(). The serialization method can be set using session.serialize_handler.
This function has no parameters.
Returns the contents of the current session encoded, or false on failure.
Must call session_start() before using session_encode().
session_encode() just return the session dataset in a formatted form
session_start();
$_SESSION['login_ok'] = true;
$_SESSION['nome'] = 'sica';
$_SESSION['inteiro'] = 34;
echo session_encode();
this code will print
login_ok|b:1;nome|s:4:"sica";inteiro|i:34;
