PHP 怎麼執行mongodb 的 $in 和$size查詢

假設有個這樣的集合

{ "_id" : ObjectId("5022518d09248743250688e0"), "name" : "big fruit", "fruits" : [ "apple", "pear", "orange" ] } ， { "_id" : ObjectId("502251a309248743250688e1"), "name" : "good fruit", "fruits" : [ "banana", "pear", "orange" ] }  ，{ "_id" : ObjectId("502251c109248743250688e2"), "name" : "good fruit", "fruits" : [ "banana", "apple", "tomato" ] }  

假設有這樣的集合

RT 者兩句代碼用PHP怎麼寫

db.coll.find({_id:{$in[ ObjectId("502251a309248743250688e1"), ObjectId("502251c109248743250688e2")]}})

查詢長度為三的數組

db.coll.find({fruits:{$size：0}})

用PHP的話要怎麼實現
