Using PHP to find specific entry in JSON URL response - php

Question

I am trying to find out whether a user is part of a Steam group. To do this, I'm using Steam's Web API, and using URL:
https://api.steampowered.com/ISteamUser/GetUserGroupList/v1/?key=APIKEYHERE&steamid=STEAMID64HERE
To get a JSON response of all groups that a user is part of.
Now I want to find out if they're part of my specific group with ID: 1111111 using PHP.
How would one do that? Currently I have the code being decoded like so:
$groupid = "1111111";
$url = "https://api.steampowered.com/ISteamUser/GetUserGroupList/v1/?key=APIKEYHERE&steamid=STEAMID64HERE";
$result = file_get_contents($url);
// Will dump a beauty json :)
$pretty = json_decode($result, true);
This makes the $pretty variable contain the entire JSON response.
How would I use PHP to find the group ID in a response that looked like this?
{
"response": {
"success": true,
"groups": [
{
"gid": "4458711"
},
{
"gid": "9538146"
},
{
"gid": "11683421"
},
{
"gid": "24781197"
},
{
"gid": "25160263"
},
{
"gid": "26301716"
},
{
"gid": "29202157"
},
{
"gid": "1111111"
}
]
}
}
Can't figure it out.
Any help? :)

Answer 1

Use the below code to check whether user is exist in the response or not
$groupid = "1111111";
$is_exists = false;
$url = "https://api.steampowered.com/ISteamUser/GetUserGroupList/v1/?key=APIKEYHERE&steamid=STEAMID64HERE";
$result = file_get_contents($url);
// Will dump a beauty json :)
$pretty = json_decode($result, true);
foreach ($pretty['response']['groups'] as $key => $value) {
if($value['gid'] == $groupid) {
$is_exists = true;
break;
}
}
// check is_exists
Check that above variable $is_exists for true or false

$groupid = "1111111";
$url = "https://api.steampowered.com/ISteamUser/GetUserGroupList /v1/?key=APIKEYHERE&steamid=STEAMID64HERE";
$result = file_get_contents($url);
// Will dump a beauty json :)
$pretty = json_decode($result);
$s = $pretty->response->groups;
foreach($s as $value)
{
if((int) $groupid == $value->gid)
{
echo "Found";
}else
{
echo "Not found";
}
}
