soap function not returning string in php
You would need to set CURLOPT_RETURNTRANSFER to get the result on success.
Add this line before curl_exec
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);curl_exec() returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.
