问题描述

我需要在多维数组上运行一个foreach脚本。

原始的JSON格式如下:

  {
_links:{

},
chatter_count:15,
chatters:{
moderators:[
moderator1 ,
moderator2,
moderator3
],
staff:[
staff1,
staff2,
staff3
],
admins:[
admin1,
admin2,
admin3
],
global_mods:[
global_mod1,
global_mod2,
global_mod3
],
查看者:[
viewer1,
viewer2,
viewer3
]
}
}
json_decode 得到一个PHP数据结构,我现在已经失去了如何运行一个foreach循环来输出像这样:

  chatter_count:15 

版主:
版主1
版主2
版主3

职员:
职员1
职员2
职员3

管理员:
admin1
admin2
admin3

global_mods:
global_mod1
global_mod2
global_mod3
$ b查看者:
viewer1
viewer2
viewer3


解决方案

首先将json解码为数组,然后利用 $ key 打印数组:

 <?php 

$ testobj = json_decode(file_get_contents('https://tmi.twitch.tv/group/user/sodapoppin/chatters'),true);

echochatter_count:。$ testobj ['chatter_count']。\\\
;
$ b foreach($ testobj ['chatters'] as $ key => $ chatter){
echo\\\
$ key:\\\
;
foreach($ chatter as $ value){
echo$ value\\\
;




输出: p>

我从你给的URL得到这样的东西:

  chatter_count: 5461

I need to run a foreach script on a multi-dimensional array.

The original JSON is formatted like:

{
    "_links":{

    },
    "chatter_count":15,
    "chatters":{
        "moderators":[
            "moderator1",
            "moderator2",
            "moderator3"
        ],
        "staff":[
            "staff1",
            "staff2",
            "staff3"
        ],
        "admins":[
            "admin1",
            "admin2",
            "admin3"
        ],
        "global_mods":[
            "global_mod1",
            "global_mod2",
            "global_mod3"
        ],
        "viewers":[
            "viewer1",
            "viewer2",
            "viewer3"
        ]
    }
}

Having run json_decode to get a PHP data structure, I'm now lost on how to run a foreach loop to output something like:

chatter_count: 15

moderators:
moderator1
moderator2
moderator3

staff:
staff1
staff2
staff3

admins:
admin1
admin2
admin3

global_mods:
global_mod1
global_mod2
global_mod3

viewers:
viewer1
viewer2
viewer3
解决方案

First decode the json to array, then make use of $key to print the array:

<?php

$testobj = json_decode(file_get_contents('https://tmi.twitch.tv/group/user/sodapoppin/chatters'), true);

echo "chatter_count:".$testobj['chatter_count']."\n";

foreach($testobj['chatters'] as $key => $chatter){
    echo "\n$key:\n";
    foreach ($chatter as $value) {
        echo "$value\n";
    }
}

Output:

I get something like this from the URL you gave:

chatter_count:5461

moderators:
emilydk
fyzicul
hnl
hnlbot
ngmack
nixi93
psychostatik
sodapoppin
staystrong420
sxyhxy
tastyphone

staff:
evoli
pluto
...
...
