How to set up an API in a contact to automatically add posts?

Question

API

I'm trying to set up automatic publication of posts to a group.
When running on a local server - 'success!' but nothing is added to the group, what's wrong?
post_data.text
"Тестовое сообщение"
token.txt:
'токен из 85 символов" // получен из группы
wall.post.php

<meta http-equiv="content-type" content="text/html; charset="utf-8">


<?php

$group_id = '-9894839';   
$token = file_get_contents('token.txt');
$api_ver = "5.80";
$text = file_get_contents('post_data.txt');
$url = sprintf('https://api.vk.com/method/wall.post?');
$ch = curl_init();

curl_setopt_array( $ch, array(
    CURLOPT_POST 		   => TRUE,
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_SSL_VERIFYPEER => FALSE,
    CURLOPT_SSL_VERIFYHOST => FALSE,
    CURLOPT_POSTFIELDS     => array(
    "owner_id"	    => $group_id,
    "form_group" => 1,
    "message"  	    =>$text,
    "access_token"  =>$token,
    "v"             =>$api_ver,

),
    CURLOPT_URL =>$url,
    ));
$query = curl_exec($ch);
curl_close($ch);
if(!$query){
  printf('Error');
  exit;
}
else{
  printf('$success');
  exit;
}

wall.get gets posts from group
wall.post publishes
