PHP操作MongoDB打模組 linux下,詳細介紹(七),mongodblinux




                   

                    




linux系統,為何剛連到mongodb又馬上退出了?

connect failed,根本沒連上,不是剛連上又退出。
看一下mongod有沒有正常運行吧,看看log,進程,連接埠。
 
php操作mongoDB資料庫查詢的時怎寫“或”這樣的多個條件查詢代碼?

據我所知,目前mongoDB沒有“或”這個東西

但我剛才在網上查了下
發現了下面的資訊,你參考下吧

在mongodb中有$or 操作符的,官網中給出的例子如下:

Simple:

db.foo.find( { $or : [ { a : 1 } , { b : 2 } ] } )

With another field

db.foo.find( { name : "bob" , $or : [ { a : 1 } , { b : 2 } ] } )

The $or operator retrieves matches for each or clause individually and eliminates duplicates when returning results. A number of $or optimizations are planned for 1.8. See this thread for details.
$or cannot be nested.
