Php get data with api key - php

Question

I want to make a PHP page for sending like with API from social media panel which I have a membership.
They give me this example but I don't understand completely.
Example Code:
<?php
class Api
{
public $api_url = 'http://domain/api/v2'; // API URL
public $api_key = ''; // Your API key
public function order($data) { // add order
$post = array_merge(array('key' => $this->api_key, 'action' => 'add'), $data);
return json_decode($this->connect($post));
}
public function status($order_id) { // get order status
return json_decode($this->connect(array(
'key' => $this->api_key,
'action' => 'status',
'id' => $order_id
)));
}
public function services() { // get services
return json_decode($this->connect(array(
'key' => $this->api_key,
'action' => 'services',
)));
}
public function balance() { // get balance
return json_decode($this->connect(array(
'key' => $this->api_key,
'action' => 'balance',
)));
}
private function connect($post) {
$_post = Array();
if (is_array($post)) {
foreach ($post as $name => $value) {
$_post[] = $name.'='.urlencode($value);
}
}
$ch = curl_init($this->api_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
if (is_array($post)) {
curl_setopt($ch, CURLOPT_POSTFIELDS, join('&', $_post));
}
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)');
$result = curl_exec($ch);
if (curl_errno($ch) != 0 && empty($result)) {
$result = false;
}
curl_close($ch);
return $result;
}
}
// Examples
$api = new Api();
$services = $api->services(); # return all services
$balance = $api->balance(); # return user balance
// add order
$order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'quantity' => 100)); # Default
$order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'quantity' => 100, 'keywords'=>"test, testing")); # SEO
$order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'comments' => "good pic\ngreat photo\n:)\n;)")); # Custom Comments
$order = $api->order(array('service' => 4, 'link' => 'http://example.com/test', 'quantity' => 100, 'usernames'=>"test, testing", 'hashtags'=>"#goodphoto")); # Mentions with Hashtags
$order = $api->order(array('service' => 5, 'link' => 'http://example.com/test', 'usernames' => "test\nexample\nfb")); # Mentions Custom List
$order = $api->order(array('service' => 6, 'link' => 'http://example.com/test', 'quantity' => 100, 'hashtag'=>"test")); # Mentions Hashtag
$order = $api->order(array('service' => 7, 'link' => 'http://example.com/test', 'quantity' => 1000, 'username'=>"test")); # Mentions User Followers
$order = $api->order(array('service' => 8, 'link' => 'http://example.com/test', 'quantity' => 1000, 'media'=>"http://example.com/p/Ds2kfEr24Dr")); # Mentions Media Likers
$order = $api->order(array('service' => 9, 'link' => 'http://example.com/test', 'quantity' => 1000, 'usernames'=>"test")); # Mentions
$order = $api->order(array('service' => 10, 'link' => 'http://example.com/test')); # Package
$order = $api->order(array('service' => 12, 'link' => 'http://example.com/test', 'quantity' => 100, 'runs' => 10, 'interval' => 60)); # Drip-feed
$order = $api->order(array('service' => 11, 'username' => 'username', 'min' => 100, 'max' => 110, 'posts' => 0,'delay' => 30)); # Subscriptions
$status = $api->status($order->order); # return status, charge, remains, start count
?>
For now, I want to see "get balance" on my PHP page but I couldn't do. I fill API URL and API key. Could you help me how can I do?
Thanks

You would use the API by calling balance() on it, like so;
$api = new Api();
$response = $api->balance();
// The response has "balance" and "currency" properties, which can be accessed like so;
echo "Your balance is " . $response->balance . " " . $response->currency;
