$url = 'http://'; //调用接口的平台服务地址
$post_string = array('a'=>'b');
$ch = curl_init();
$this_header = array(
"content-type: application/x-www-form-urlencoded;
charset=UTF-8"
);
curl_setopt($ch,CURLOPT_HTTPHEADER,$this_header);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$result = curl_exec($ch);
if($result)
echo "<script>\nalert(\"同步成功！ \");\n</script>";
curl_close($ch);

Summary: To solve this kind of encoding problem, firstly, confirm what the encoding is in the two places. Secondly, if the encoding is the same, it can be sent directly. When using curl, you need to add Set the charset in the header. Finally, check and try more. If one method doesn't work, try another one.
