Run a php foreach loop on multi-dimensional array - php

Question

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

Answer 1

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
...
...
...

You are just few step behind what you're trying to accomplish. To get chatter_count use $testobj ->chatter_count. And then loop through your chatters array use foreach($testobj->chatters as $key => $value) { // write your logic here }. This way you can get what you're trying to accomplish. I can paste the code here, but I would like you to give a try first. Hope you get your hints now.

PHP
$data = json_decode($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";
}

Try this code.
And you have to add some style for print.
$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);
}
}
Hoping this helps you.
