我需要在多维数组上运行foreach脚本。
原始JSON的格式如下:
{
"_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"
],
"viewers":[
"viewer1",
"viewer2",
"viewer3"
]
}
}
运行json_decode
来获取PHP数据结构后,我现在迷失了如何运行foreach循环来输出类似的内容:
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

首先将json解码为数组,然后使用$key
打印数组:
<?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";
}
}

我从您提供的网址中获得了类似的内容:
chatter_count:5461
moderators:
emilydk
fyzicul
hnl
hnlbot
ngmack
nixi93
psychostatik
sodapoppin
staystrong420
sxyhxy
tastyphone
staff:
evoli

你只是落后于你想要完成的事情。要chatter_count
使用$testobj ->chatter_count
。然后循环使用chatters
数组使用foreach($testobj->chatters as $key => $value) { // write your logic here }
。通过这种方式,您可以获得您想要完成的任务。我可以在这里粘贴代码,但我希望您先尝试一下。希望你现在得到你的提示。

$data = json_decode($json, true);
echo "chatter_count: " . $data["chatter_count"] . "\n";
foreach($data['chatters'] as $chattersK=> $chatters) {
echo $chattersK . ":\n";
foreach($chatters as $chatterK => $chatters) {
echo $chatters . "\n";
}
echo "\n";
}

试试这段代码 你必须添加一些打印样式。
$testobj = json_decode(file_get_contents("https://tmi.twitch.tv/group/user/sodapoppin/chatters"));
print("chatter_count:", $testobj->chatter_count);
foreach ( $testobj->chatters as $key=>$chatter )
{
print $key;
foreach($chatter as $values){
printf("%s\n", $values);
}
}
希望这会对你有所帮助。
