If You observe the Switch Case you will see that it takes a variable $status which is a substring of a particular key of an array.

Anyways basically what is does is interrogate the substring of another string. So the logic is based on the content of that substr saved in variable $status if it is DELIVRD means that switch will give Delivered status to $s and so on so forth.

The turkish word that you got is the default value given to the variable by switch if none of the above conditions are met.

So most probably the Turkish word could have a meaning that tells you that the $status variable contains something else and not DELIVRD or UNDELIVRD.

Check the response codes from the SMPP Manual and populate the switch with all of DLR response cases.

Cheers

I am trying to get the delivery status on a particular message id, However, thats just not letting me. I tried with QuerySMS, but that gives me an error:
Warning: pack() [function.pack]: Type F: unknown format code

I'd appreciate any help here.

I would like to be able to query based on message id, so i can do my queries when the traffic is low on my smpp gates.

its work:

$message_id = $message_id.chr(0);
$message_id_len = strlen($message_id);
$source_addr_ton = $source_addr_ton.chr(0);
$source_addr_npi = $source_addr_npi.chr(0);
$source_addr = $source_addr . chr(0);
$source_addr_len = strlen($source_addr);

$pdu = pack("a{$message_id_len}cca{$source_addr_len}",$message_id,$source_addr_ton,$source_addr_npi,$source_addr);
