MongoCursor::timeout — Sets a client-side timeout for this query
A timeout can be set at any time and will affect subsequent queries on the cursor, including fetching more results from the database. For example, to wait forever for an initial response but timeout after 100 ms for subsequent results, one could say:
<?php
$cursor = $collection->find();
// $cursor->hasNext() executes the query. No timeout has been set, so the
// program will wait as long as necessary for a response.
while ($cursor->hasNext()) {
$cursor->timeout(100);
// now the timeout has been set, so if the cursor needs to get more results
// from the database, it will only wait 100 ms for the database's reply
try {
print_r($cursor->getNext());
}
catch(MongoCursorTimeoutException $e) {
echo "query took too long!";
}
}
?>
A timeout of 0 (or a negative number) will wait forever so it can be used to reset the cursor if a timeout is no longer needed.
ms
The number of milliseconds for the cursor to wait for a response. By default, the cursor will wait forever.
This cursor.
Example #1 MongoCursor::timeout() example
A query where the cursor waits for one second for a response.
<?php
$cursor = $collection->find()->timeout(1000);
try {
foreach ($cursor as $value) {
print_r($value);
}
}
catch(MongoCursorTimeoutException $e) {
echo "query took too long!";
}
?>
Causes methods that fetch results to throw MongoCursorTimeoutExceptions if the query takes longer than the number of milliseconds specified.
