                  问题描述

                  这一定很简单,但我似乎无法弄清楚...假设我有一个集合 users,这是集合中的第一项:

                  This has to be easy, but i can't seem to figure it out... Let say i had a collection users and this is the first item in the collection:

                  { 
                      "_id" : ObjectId("4d8653c027d02a6437bc89ca"), 
                      "name" : "Oscar Godson", 
                      "email" : "oscargodson@xxx.com", 
                      "password" : "xxxxxx", 
                      "tasks" : [
                      {
                          "task" : "pick up stuff",
                          "comment" : "the one stuff over there"
                      },
                      {
                          "task" : "do more stuff",
                          "comment" : "lots and lots of stuff"
                      }
                  ] }
                  

                  然后我将如何使用 MongoDB 的 PHP 驱动程序将另一个任务"添加到集合中此项的任务"数组中

                  How with the PHP driver for MongoDB would I then go and add another "task" to the "tasks" array in this item in a collection

                  推荐答案

                  使用Mongo的$push操作:

                  Use Mongo's $push operation:

                  $new_task = array(
                    "task" => "do even more stuff",
                    "comment" => "this is the new task added"
                  );
                  $collection->update(
                    array("_id" => ObjectId("4d8653c027d02a6437bc89ca")), 
                    array('$push' => array("tasks" => $new_task))
                  );
