我有一个方案
{
"_id" : ObjectId("50ec1d93ba02ece1979ee4a5"),
"url" : "google.com"
"results" : [
{ "1357651347" : { "data1" : "a", "data2" : "b", "data3" : "c" }},
{ "1357651706" : { "data1" : "d", "data2" : "e", "data3" : "f" }},
{ "1357651772" : { "data1" : "g", "data2" : "h", "data3" : "i" }}
]
}
我对 id 的结果感兴趣1357651706
。我如何获得它们(在 PHP 中)?
