我是PHP的新手，我有一个json文件，其中包含几个＆＃39;事件＆＃39;看起来如下的对象。这是一个事件＆＃39;：
"2252182": {
"id" : "2252182",
"name" : "Arsenal-Everton",
"tournament_stageFK": "844714",
"startdate" : "2017-05-21T14:00:00+00:00",
"status_type" : "notstarted",
"property" : {},
"event_participants": {
"7297686": {
"id" : "7297686",
"number" : "1",
"participantFK": "9825",
"eventFK" : "2252182",
"n" : "0",
"ut" : "2016-06-15T08:05:33+00:00",
"result" : {},
"participant" : {
"id" : "9825",
"name" : "Arsenal",
"gender" : "male",
"type" : "team",
"countryFK" : "2",
"n" : "2",
"ut" : "2016-09-15T10:44:36+00:00",
"country_name": "England"
}
},
"7297687": {
"id" : "7297687",
"number" : "2",
"participantFK": "8668",
"eventFK" : "2252182",
"n" : "0",
"ut" : "2016-06-15T08:05:33+00:00",
"result" : {
"24255418": {
"id" : "24255418",
"event_participantsFK": "7297687",
"result_typeFK" : "1",
"result_code" : "ordinarytime",
"value" : "0",
"n" : "0",
"ut" : "2016-06-15T08:05:33+00:00"
},
"24255420": {
"id" : "24255420",
"event_participantsFK": "7297687",
"result_typeFK" : "6",
"result_code" : "runningscore",
"value" : "0",
"n" : "0",
"ut" : "2016-06-15T08:05:33+00:00"
}
},
"participant" : {
"id" : "8668",
"name" : "Everton",
"gender" : "male",
"type" : "team",
"countryFK" : "2",
"n" : "2",
"ut" : "2016-09-15T10:45:47+00:00",
"country_name": "England"
}
}
}
}
我已经使用php解码成了一个php数组，但是event_participants对象没有转换成数组，或者如果它们是，当我尝试访问$fixture['event_participants'][0]时我得到{{1错误。我的代码如下：
Message: Undefined offset: 0如果我$json = json_decode(file_get_contents('assets/json/fixtures.json'),true);
foreach ($json['events'] as $fixture)
{
$tmp = array();
$tmp['group_id'] = $fixture['tournament_stageFK'];
$tmp['group_league'] = $fixture['tournament_stage_name'];
$tmp['fixture_id'] = $fixture['id'];
$tmp['fixture_name'] = $fixture['name'];
$tmp['fixture_date'] = $fixture['startdate'];
$tmp['fixture_status'] = $fixture['status_type'];
$tmp['event_participants'] = $fixture['event_participants'];
if (isset($fixture['event_participants'])) {
print_r($fixture['event_participants'][0]);
}
}
我希望收到：
$fixture['event_participants'][0]所以我回答了自己的问题 - array_values解决了我的问题：
{
"id" : "7297686",
"number" : "1",
"participantFK": "9825",
"eventFK" : "2252182",
"n" : "0",
"ut" : "2016-06-15T08:05:33+00:00",
"result" : {},
"participant" : {
"id" : "9825",
"name" : "Arsenal",
"gender" : "male",
"type" : "team",
"countryFK" : "2",
"n" : "2",
"ut" : "2016-09-15T10:44:36+00:00",
"country_name": "England"
}
}
