   //'icon_emoji'  => $icon,
   //'attachments' => $attachments
);

echo "--- pass --->>" . PHP_EOL;
echo print_r($data, true) . PHP_EOL;

$data_string   = json_encode($data);
$ch = curl_init($slack->slack_url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
   'Content-Type: application/json',
   'Content-Length: ' . strlen($data_string))
);
$result = null;
try {
   //Execute CURL
   $result = curl_exec($ch);
