As header for Cc does allow multiple emails you can just put it in there as string separated by commas:

$coauthordata = implode(",",$coauthordata);

This should allow you to send it to multiple Cc's.

Or just replace your line:

$strRawMessage .= "Cc:" .  $coauthordata  . "\r\n";

for

$strRawMessage .= "Cc:" .  implode(",",$coauthordata)  . "\r\n";
