我一直在尝试找出如何从json数组中提取多个JSON对象.

i've been trying to figure out how to extract multiple JSON objects from a json array.

我在其他帖子中使用了此代码

I used this code from other post

$json = '[ {"user_id":"1", "user_name":"Sayeed Amin", "time":"2019-11-06 13:21:26"} ]'; $someArray = json_decode($json, true); foreach ($someArray as $key => $value) { echo $value["user_id"] . ", " . $value["user_name"] . ", " . $value["time"] . "<br>"; }

我可以将其用于数组内的单个json对象，效果很好.

I can use this for a single json object inside an array, the result is good.

结果: 1，Sayeed Amin，2019-11-06 13:21:26

如果我在数组和数组中有多个json对象，该怎么办?喜欢

How about if i have multiple json objects inside and array? like

$json = '[ {"name":"Name", "value":"me you", "id":0, "type":"name", "first":"me", "middle":"", "last":"you" }, {"name":"Email", "value":"myemail@gmail", "id":1, "type":"email" }, {"name":"Phone", "value":"+12015550000", "id":2,"type":"phone" }, {"name":"Address", "value":"my address\nsomecity, somestate\nsomepost\nUS", "id":3, "type":"address", "address1":"my address", "address2":"", "city":"somecity", "state":"somestate", "postal":"somepost", "country":"US" } ]'; $someArray = json_decode($json, true); foreach ($someArray as $key => $value) { echo $value["name"] . ", " . $value["value"] . "<br>"; }

结果:名字，我，你电子邮件，myemail @ gmail 电话，+ 12015550000 地址，我的地址，某个城市，某个州，某个职位，美国

所需结果:我叫你，

推荐答案

如果您只想输出对象数组的首次出现，则可以像这样对数组进行适当寻址

If you only want to output the First Occurance of the array of objects then address the array appropriately like

$json = '[ {"name":"Name", "value":"me you", "id":0, "type":"name", "first":"me", "middle":"", "last":"you" }, {"name":"Email", "value":"myemail@gmail", "id":1, "type":"email" }, {"name":"Phone", "value":"+12015550000", "id":2,"type":"phone" }, {"name":"Address", "value":"my address\nsomecity, somestate\nsomepost\nUS", "id":3, "type":"address", "address1":"my address", "address2":"", "city":"somecity", "state":"somestate", "postal":"somepost", "country":"US" } ]'; $arr = json_decode($json); echo $arr[0]->name . ", " . $arr[0]->value . "\n";

结果

Name, me you
