SessionHandlerInterface::read
(PHP 5 >= 5.4.0, PHP 7, PHP 8)
SessionHandlerInterface::read — Read session data
Descrizione
This method is called by PHP itself when the session is started.
This method should retrieve the session data from storage by the
session ID provided. The string returned by this method must be in the same
serialized format as when originally passed to the SessionHandlerInterface::write()
If the record was not found, return false
.
The data returned by this method will be decoded internally by PHP using the
unserialization method specified in session.serialize_handler.
The resulting data will be used to populate the $_SESSION superglobal.
Note that the serialization scheme is not the same as unserialize()
and can be accessed by session_decode().
