To ensure that a remove occurred successfully use MongoDB::lastError(). Currently MongoGridFS::remove will return even if the remove failed.
MongoGridFS::remove
(PECL mongo >=0.9.0)
MongoGridFS::remove — Remove files and their chunks from the database
说明
public MongoGridFS::remove
([ array
$criteria = array()
[, array $options = array()
]] ) : bool|array参数
-
criteria -
The filename or criteria for which to search.
-
options -
An array of options for the remove operations executed against the
chunksandfilescollections. See MongoCollection::remove() for documentation on these options.
返回值
Returns an array containing the status of the removal (with respect to the
files collection) if the "w" option is
set. Otherwise, returns TRUE.
Fields in the status array are described in the documentation for MongoCollection::insert().
错误／异常
Throws MongoCursorException if the "w" option is set and the write fails.
Throws MongoCursorTimeoutException if the "w" option is set to a value greater than one and the operation takes longer than MongoCursor::$timeout milliseconds to complete. This does not kill the operation on the server, it is a client-side timeout. The operation in MongoCollection::$wtimeout is milliseconds.
