致命的錯誤：調用未定義的函數聚合（）

Question

我把mongo放在我的Mac上使用複製mongo.so 5.2和5.4 mongoCollection沒有聚合方法！ 我測試了同樣的php在我的aws上，並在那裏工作

我試過var_dump(get_class_methods('MongoCollection')); 和我的地方：

array (size=24) 
0 => string '__construct' (length=11) 
1 => string '__toString' (length=10) 
2 => string '__get' (length=5) 
3 => string 'getName' (length=7) 
4 => string 'getSlaveOkay' (length=12) 
5 => string 'setSlaveOkay' (length=12) 
6 => string 'drop' (length=4) 
7 => string 'validate' (length=8) 
8 => string 'insert' (length=6) 
9 => string 'batchInsert' (length=11) 
10 => string 'update' (length=6) 
11 => string 'remove' (length=6) 
12 => string 'find' (length=4) 
13 => string 'findOne' (length=7) 
14 => string 'ensureIndex' (length=11) 
15 => string 'deleteIndex' (length=11) 
16 => string 'deleteIndexes' (length=13) 
17 => string 'getIndexInfo' (length=12) 
18 => string 'count' (length=5) 
19 => string 'save' (length=4) 
20 => string 'createDBRef' (length=11) 
21 => string 'getDBRef' (length=8) 
22 => string 'group' (length=5) 
23 => string 'distinct' (length=8)` 

和AWS：

array(28) { [0]=> string(11) "__construct" [1]=> string(10) "__toString" [2]=> string(5) "__get" [3]=> string(7) "getName" [4]=> string(12) "getSlaveOkay" [5]=> string(12) "setSlaveOkay" [6]=> string(17) "getReadPreference" [7]=> string(17) "setReadPreference" [8]=> string(4) "drop" [9]=> string(8) "validate" [10]=> string(6) "insert" [11]=> string(11) "batchInsert" [12]=> string(6) "update" [13]=> string(6) "remove" [14]=> string(4) "find" [15]=> string(7) "findOne" [16]=> string(13) "findAndModify" [17]=> string(11) "ensureIndex" [18]=> string(11) "deleteIndex" [19]=> string(13) "deleteIndexes" [20]=> string(12) "getIndexInfo" [21]=> string(5) "count" [22]=> string(4) "save" [23]=> string(11) "createDBRef" [24]=> string(8) "getDBRef" [25]=> string(5) "group" [26]=> string(8) "distinct" [27]=> string(9) "aggregate" }

當我使用終端（本地）骨料它的工作原理

似乎很奇怪，任何想法表示讚賞。

Answer 1

MongoCollection::aggregate (PECL mongo >=1.3.0)

這樣 - 你正在使用的驅動程序版本> = 1.3.0在AWS上，並< 1.3.0在Mac上。

注意aggregation was introduced in monogoDB version 2.2
