public bool|array MongoGridFS::delete ( mixed $id )

MongoGridFS::delete() is a convenience method for calling MongoGridFS::remove() with specific criteria and default options parameters.

参数

id: _id of the file to remove.

返回值

Returns an array containing the status of the removal (with respect to the files collection) if a write concern is applied. 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.
