Api key ve api url kısmını $ayarcek['api_key'], $ayarcek['api_url'] kodları ile admin panelden çekmesini istiyorum bunu nasıl yapabilirim?
 <?php class Api
{

public $api_url = "APİ URL";

public $api_key = "APİ KEY";

public function order($data) { // yeni sipariş
$post = array_merge(array('key' => $this->api_key, 'action' => 'add'), $data);
return json_decode($this->connect($post));
}

public function status($order_id) { // sipariş durumu
return json_decode($this->connect(array(
'key' => $this->api_key,
'action' => 'status',
'order' => $order_id
)));
}

public function services() { // servis listesi
return json_decode($this->connect(array(
'key' => $this->api_key,
'action' => 'services'
)));
}

public function balance() { // bakiye sorgulama
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;
}
}

// Örnekler

$api = new Api();

$services = $api->services(); # Servis Listesi

$balance = $api->balance(); # Bakiye Sorgulama



// Yeni Sipariş

$order = $api->order(array('service' => $ayarcek["api_numara"], 'link' => $_POST["url"], 'quantity' => $_POST["adet"]));
?>
