使用PHP curl发送UTF-16编码数据

Question

I'm building a php client to a web service that requires posted data to be encoded as UTF-16. How do i configure curl to encode my data in UTF-16 and also to decode the answer in UTF-16?

Some sample code:

$s = curl_init($url);

curl_setopt($s,CURLOPT_POST,1); 
curl_setopt($s,CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($s,CURLOPT_POSTFIELDS,$data);
curl_setopt($s,CURLOPT_TIMEOUT, 5);
curl_setopt($s,CURLOPT_HTTPHEADER,array('Content-Type: text/plain'));

$result = curl_exec($s);
curl_close($s);

Adding an Accept-Encoding header does not seem to do the trick. Is it possible to encode my $data string in UTF-16 first and then pass a byte array to curl instead of a string?

Thank you for your answers!

First, you need to find out what's your data encoding. Then, it's your choice. Both iconv() and mb_convert_encoding() work pretty well.

Additionaly, you should inform about the encoding in the HTTP header:

curl_setopt($s,CURLOPT_HTTPHEADER,array('Content-Type: text/plain; charset=UTF-16'));
