How to write a variable?

Question

PHP

Execute the request

$friends_getRequests = curl( 'https://api.vk.com/method/friends.getRequests?offset=1&count=1&extended=1&need_viewed=1&access_token='.$token);

In response we get

{"response":[{"uid":33224900},{"uid":205869219},{"uid":321678938},{"uid":364608800},{"uid":360153341},{"uid":361830009},{"uid":277374452},{"uid":232364661},{"uid":81323385},{"uid":345063168},{"uid":359946852},{"uid":348982141},{"uid":19482073},{"uid":217818751},{"uid":275193481}]}

How exactly to write the first id into the $user_1 variable?

Answer 1

$response = '{"response":[{"uid":33224900},{"uid":205869219},{"uid":321678938},{"uid":364608800},{"uid":360153341},{"uid":361830009},{"uid":277374452},{"uid":232364661},{"uid":81323385},{"uid":345063168},{"uid":359946852},{"uid":348982141},{"uid":19482073},{"uid":217818751},{"uid":275193481}]}';
$data = json_decode($response, true);
if (json_last_error() === JSON_ERROR_NONE && isset($data['response'][0]['uid'])) {            
    $user_1 = $data['response'][0]['uid'];
}

Answer 2

This is a string in JSON format, it must be parsed using json_decode, there are examples and lessons on the Internet.

Answer 3

Something like this:

$s = '{"response":[{"uid":33224900},{"uid":205869219},{"uid":321678938},{"uid":364608800},{"uid":360153341},{"uid":361830009},{"uid":277374452},{"uid":232364661},{"uid":81323385},{"uid":345063168},{"uid":359946852},{"uid":348982141},{"uid":19482073},{"uid":217818751},{"uid":275193481}]}';

$json = json_decode($s);
$user_1 = $json->{'response'}[0]->{'uid'};

echo($user_1);

Answer 4

I'll write a little more. First you need to check if the json is parsed correctly and no errors have occurred, and then iterate over each user and get an array of their id.

$s = '{"response":[{"uid":33224900},{"uid":205869219},{"uid":321678938},{"uid":364608800},{"uid":360153341},{"uid":361830009},{"uid":277374452},{"uid":232364661},{"uid":81323385},{"uid":345063168},{"uid":359946852},{"uid":348982141},{"uid":19482073},{"uid":217818751},{"uid":275193481}]}';

$json = json_decode($s);
$users = array();

if (!json_last_error())
{
    foreach($json->response as $user)
    {
        $users[] = $user->uid;        
    }
}

var_dump($users);
