Simple Button with PHP script with callback_data.

$keyboard = array(
"inline_keyboard" => array(array(array(
"text" => "button",
"callback_data" => "button_0"
)))
);
$postfields = array(
'chat_id' => "$chat_id",
'text' => "$reply",
'reply_markup' => json_encode($keyboard)
);

With this sample you will generate this:
Array ( [chat_id] => 2631402392 [text] => Working [reply_markup] => {"inline_keyboard":[[{"text":"button","callback_data":"button_0"}]]} )
And then you can send this data with curl to telegram API link.
FULL PHP EXAMPLE:

$bottoken = "TELEGRAM BOT TOKEN";
$chat_id = "TELEGRAM CHAT_ID";
$reply = "Working";

$url = "https://api.telegram.org/bot$bottoken/sendMessage";
$keyboard = array(
"inline_keyboard" => array(array(array(
"text" => "button",
"callback_data" => "button_0"
)))
);
$postfields = array(
'chat_id' => "$chat_id",
'text' => "$reply",
'reply_markup' => json_encode($keyboard)
);

if (!$curld = curl_init()) {
exit;
}

curl_setopt($curld, CURLOPT_POST, true);
curl_setopt($curld, CURLOPT_POSTFIELDS, $postfields);
curl_setopt($curld, CURLOPT_URL,$url);
curl_setopt($curld, CURLOPT_RETURNTRANSFER, true);

$output = curl_exec($curld);

curl_close ($curld);

For link button you have to change callback_data to URL.

$keyboard = array(
"inline_keyboard" => array(array(array(
"text" => "button",
"url" => "http://www.google.com"
)))
);

Array ( [chat_id] => 2631402392 [text] => Working [reply_markup] => {"inline_keyboard":[[{"text":"button","url":"http:\/\/www.google.com"}]]} )

You can send link button to your telegram bot. You can add other optional fields for your InlineKeyboardButton button.
