(PECL mongo >=0.9.0)

简介

Represents a MongoDB collection.

Collection names can use any character in the ASCII set. Some valid collection names are "", "...", "my collection", and "*&#@".

User-defined collection names cannot contain the $ symbol. There are certain system collections which use a $ in their names (e.g., local.oplog.$main), but it is a reserved character. If you attempt to create and use a collection with a $ in the name, MongoDB will assert.

预定义常量

MongoCollection::ASCENDING
Ascending direction for sorts and index creation.
MongoCollection::DESCENDING
Descending direction for sorts and index creation.


Fields

db
The "parent" database for this collection.
w
The number of servers to replicate a change to before returning success. Value is inherited from the parent database. The MongoDB class has a more detailed description of how w works.
wtimeout
The number of milliseconds to wait for $this->w replications to take place. Value is inherited from the parent database. The MongoDB class has a more detailed description of how wtimeout works.
