Debuggare Bot Telegram in modo semplice

Debuggare bot telegram può essere molto ostico non potendo leggere valori stampati in pagina da var_dump() o simili a meno che non si simulino le richieste delle Bot API.
Mentre si prova a mandare la variabile in chat spesso può capitare di superare il limite di 4096 char (limite di sendMessage)
Per questo ho deciso di fare una funzione per semplificare il tutto.

Descrizione:

bool debug ( mixed $expression [, mixed $... ] )

Se esiste $chat_id manda il messaggio in quella chat, altrimenti lo manda al id settato alla costante MYID

Parametri:

expression

= La variabile che vuoi dumpare

Valori restituiti:
Sempre true

Esempi:

debug(true, $var, 123, $update);

Funzione:
function debug()
{
global $chat_id;

$args = func_get_args();

if (!isset($chat_id) or $chat_id == 0 or $chat_id == '') {
$id = MYID;
} else {
$id = $chat_id;
}

foreach ($args as $debug) {
$str = var_export($debug, true);
$array_str = str_split($str, 4050);

foreach ($array_str as $value) {
sendMessage($id, 'Debug:' . PHP_EOL . $value);
}
}

return true;
}


Come adattarla per altri framework:
- Sostituire tutti i $chat_id con i chat_id.
- Sostituire sendMessage(chat_id, text) con la vostra sendmessage, ed eventualmente aggiustare l'ordine dei parametri.
- Settare o sostituire MYID con il vostro id.

Ho recentemente scoperto grazie a @Parsec82 che si possono mandare file tramite bot usando i link dei canali pubblici anzichè usare il file id.
