MongoCursor::setFlag — Sets arbitrary flags in case there is no method available the specific flag
The MongoCursor class has several methods for setting flags on the query object. This method is available in case the MongoDB wire protocol has acquired a new flag, and the driver has not been updated with a method for this new flag. In all other cases, the method should be used. See the "See also" section for available methods.
flag
Which flag to set. You can not set flag 3 (OPLOG REPLAY) or flag 6 (EXHAUST) as the driver does not know how to handle them. You will get a warning if you try to use those. For available flags, please refer to the wire protocol » documentation.
set
Whether the flag should be set (TRUE) or unset (FALSE).
Returns this cursor.
Shows a warning when an unsupport flag is attempted to be set.
Example #1 MongoCursor::setFlag() example
<?php
$m = new MongoClient( 'mongodb://localhost:13000', array( 'replSet' => 'seta' ) );
$c = $m->local->selectCollection( 'oplog.rs' );
$cursor = $c->find( array( 'ns' => 'demo.article', 'op' => 'i' ) );
$cursor->setFlag( 1, true ); // sets the tailable flag
$cursor->setFlag( 5, true ); // sets the await data flag
?>
