Tell me why this code doesn't work?

There's been a mistake, a mistake, that I'm not adding the elements wrong to the $arOptions, and I finally decided to give up this whole thing, and I'm just making a direct request to CUrl, the final work code:

<?php 
    require "../db.php";       
$urlApi = 'http://my_ip/api';
$token = 'mytoken';

// Забираем пользователя и изменяем его id, чтобы нельзя было обратится за другого
$login = $_SESSION['logged_user']-&gt;login;
$var = R::findOne('users', 'WHERE `login`=?', [$login]);

$ch = curl_init();

$data = array(); 

$arOptions = [
    CURLOPT_SSL_VERIFYPEER =&gt; false,
    CURLOPT_SSL_VERIFYHOST =&gt; false,
    CURLOPT_HEADER =&gt; true,
    CURLOPT_RETURNTRANSFER =&gt; true,
    CURLOPT_HTTPHEADER =&gt; [
        'x-inclo-token:' . $token,
        'Accept: application/json',
        'Content-Type: application/json'
    ],
];

if (isset($_POST)){ 
    foreach($_POST as $key =&gt; $value){ // Разбираем массив $_POST
        if ($key == 'url_api'){
            $urlApi = $urlApi . $value;
            curl_setopt($ch, CURLOPT_URL, $urlApi);
        }
        if ($key == 'type'){ 
            if ($value == 'post'){
                curl_setopt($ch, CURLOPT_POST, true);
                $MyFlag = 1;
            }else if($value == 'get'){ 
                curl_setopt($ch, CURLOPT_GET, true);
                $MyFlag = 0;
            }
        }
        $data[$key] = $value;
        // $a[$key]=$value; 
    }
    $data['id'] = $var-&gt;id;
}    
if ($MyFlag == 1){
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data, JSON_UNESCAPED_UNICODE));
}
curl_setopt_array($ch, $arOptions);
$res = curl_exec($ch);
curl_close($ch);     
$res = json_encode($res, JSON_UNESCAPED_UNICODE);
echo ($res);

?>

I'd be very grateful for your ideas optimizing the code.
