$clientid = 'clientidcode';
$sender = 'Demo Acc';
$message_type = 'TEXT';
$receiver = '1234567890123';

I'm "pretty sure" you don't need the ? unless your source tells you so, it's not a standard HTTP query string.

It doesn't matter what language you're doing this in, curl will always spit out stats via command line when run. I would venture to guess something in curl is balking at the request, OR the recipient of the request is returning an empty response. An example, if you curl a secure credit card processor, and the request doesn't come from an SSL-enabled site, it will return an empty string, leaving $response blank.

Try running it from the command line . . .

php -f full/path/to/yourscript.php

Barring that, see what you can get from curl_get_info() [us2.php.net]
