I'm curious about the implications of the WAIT and NO WAIT as well as READ ONLY and READ WRITE options when setting transaction isolation level as I've not been able to find a specification for what it does.
I've only seen it presented as follows:
$options = array('wait' => 'WAIT', 'rw' => 'READ WRITE');
$options = array('wait' => 'NO WAIT', 'rw' => 'READ ONLY');
$mdb2->setTransactionIsolation($isolation_level, $options);
Any input or reference to where I can read up on it would be appreciated.
