## Usage


### Creating a simple bot
```php
<?php

require_once './src/PHPTelebot.php';
$bot = new PHPTelebot('TOKEN', 'BOT_USERNAME'); // Bot username is optional, its required for handle command that contain username (/command@username) like on a group.

// Simple command
$bot->cmd('*', 'Hi, human! I am a bot.');

// Simple echo command
$bot->cmd('/echo|/say', function ($text) {
    if ($text == '') {
        $text = 'Command usage: /echo [text] or /say [text]';
    }
    return Bot::sendMessage($text);
});

// Simple whoami command
$bot->cmd('/whoami|!whoami', function () {
    // Get message properties
    $message = Bot::message();
    $name = $message['from']['first_name'];
    $userId = $message['from']['id'];
    $text = 'You are <b>'.$name.'</b> and your ID is <code>'.$userId.'</code>';
    $options = [
        'parse_mode' => 'html',
        'reply' => true
    ];

    return Bot::sendMessage($text, $options);
});

$bot->run();
```
Then run
```shell
php file.php
```

You can also see my other [sample](https://github.com/radyakaze/phptelebot/blob/master/sample.php).

*NOTE:*
- If function parameters is more than one, PHPTelebot will split text by space.
- If you don't set chat_id on options bot will send message to current chat.
- If you add option **reply => true**, bot will reply current message (Only work if you don't set custom chat_id and reply_to_mesage_id).

## Commands

Use `$bot->cmd(<command>, <function>)` to handle command.
```php
// simple answer
$bot->cmd('*', 'I am a bot');

// catch multiple commands
$bot->cmd('/start|/help', function () {
   // Do something here.
});

// call a function name
function googleSearch($search) {
   // Do something here.
}
$bot->cmd('/google', 'googleSearch');
```
Use **&#42;** to catch any command.

#### File upload
This code will send a photo to users when type command **/upload**.
```php
// Simple photo upload
$bot->cmd('/upload', function () {
    $file = '/path/to/photo.png'; // File path, file id, or url.
    return Bot::sendPhoto($file);
});
```

## Events

Use `$bot->on(<event>, <function>)` to handle all possible PHPTelebot events.

To handle inline message, just add:
```php
$bot->on('inline', function($text) {
    $results[] = [
        'type' => 'article',
        'id' => 'unique_id1',
        'title' => $text,
        'message_text' => 'Lorem ipsum dolor sit amet',
    ];
    $options = [
        'cache_time' => 3600,
    ];

    return Bot::answerInlineQuery($results, $options);
});
```
Also, you can catch multiple events:
```php
$bot->on('sticker|photo|document', function() {
  // Do something here.
 });
```
