sms - php - inserting multiple variable in an URL for the same parameter -

hi im trying sms feature site. code works well.

https://www.isms.com.my/isms_send.php?un=xxx&pwd=xxx&dstno=".$number."&msg=".rawurlencode($txt)."&type=1" 

although code doesn't

https://www.isms.com.my/isms_send.php?un=xxx&pwd=xxx&dstno=".$number."&msg=".$msg."%0a".rawurlencode($txt)."&type=1" 

as can see in &msg= im trying send 2 variable site tells me there error of missing parameter. how can input 2 variable same parameter?

i guess want send multi line text message $msg on first line , $txt on second.

as per sparse documentation end of line character %0d instead of %0a.

one other remark: documenation states msg parameter must url encode, shouldn't use rawurlencode($msg) well.

so, in code should like:

"https://www.isms.com.my/isms_send.php?     un=xxx&     pwd=xxx&     dstno=".$number."&     msg=".rawurlencode($msg)."%0d".rawurlencode($txt)."&     type=1" 

note: i've put on multiple lines readability only.
