假设我有这个JSON:
{
"achievement": [
{
"title": "Ready for Work",
"description": "Sign up and get validated",
"xp": 50,
"difficulty": 1,
"level_req": 1
},
{
"title": "All Around Submitter",
"description": "Get one piece of textual content approved in all five areas.",
"xp": 500,
"difficulty": 2,
"level_req": 1
}
}
我正在尝试通过PHP:
$string = file_get_contents("achievements.json");
$json_a=json_decode($string,true);
$getit = $json_a->achievement['title'][1];
我正试图获得成就的第一个“id”,即READY FOR WORK
。
我该如何解决这个问题?

当您将json_decode
的第二个参数设置为true
时,它将返回一个数组。
$json_a=json_decode($string,true);
返回一个数组。
$getit = $json_a['achievement'][1]['title'];
