(PECL mongo >=1.5.0)
Executes the command and resets the cursor to the start of the result set
public array MongoCommandCursor::rewind ( void )
If the cursor has already started iteration, the command will be re-executed.
Returns:
The raw server result document.
Exception:
Throws MongoConnectionException if it cannot reach the database and MongoCursorTimeoutException if the timeout is exceeded.
Throws MongoCursorException if the cursor was created with MongoCommandCursor::createFromDocument() and has already started iteration. Such cursors cannot be iterated multiple times, as they lack the original command necessary for re-execution.
Examples:
MongoCommandCursor::rewind()
<?php $rawResult = $commandCursor->rewind(); // Command cursor is now reset to the start of the result set var_dump($rawResult); ?>
The above example will output something similar to:
array(2) { ["cursor"]=> array(3) { ["id"]=> object(MongoInt64)#5 (1) { ["value"]=> string(12) "310050110216" } ["ns"]=> string(9) "demo.test" ["firstBatch"]=> array(1) { [0]=> array(2) { ["_id"]=> object(MongoId)#6 (1) { ["$id"]=> string(24) "52f5691544670a8077b0dc51" } ["value"]=> string(2) "42" } } } ["ok"]=> float(1) }
