Re: Persistent data between two executions

You can use $_SESSION to store the object, and serialize to convert to string and reverse http://ar2.php.net/manual/en/language.oop.serialization.php // file one.php require 'user.php'; $user = new User(); $_SESSION[ 'user' ] = serialize( $user ); // file two.php require 'user.php'; // the class needs to be declared $user = unserialize( $_SESSION[ 'user' ] ); I think this is the cleanest way to do, but no the best performant. If you need performance you can use the interface serializable http://ar2.php.net/manual/en/class.serializable.php If you need a resources (like a db connection) you can implement __sleep and __wakeup in your class http://ar2.php.net/manual/en/language.oop.magic-functions.php On Wed, Jun 17, 2009 at 12:11 AM, James Colannino <james@colannino.org>wrote: > Hey everyone, > > Long time reader, not such a long time poster :-P (though I have posted > to the list occasionally in the past...) > > Anyway, I have a general question for the list.
