您必须下载 libcURL 7.21.7（或其他一些二进制兼容版本）并使用 IDN 支持重新编译它。您需要在系统中安装libidn（包括您要构建的计算机中的开发文件） libcURL)。
或者，您也可以下载最新版本的 libcURL，但在这种情况下您可能必须重新编译 PHP（或至少是 cURL 扩展）。
请注意，您还可以使用
idn_to_ascii预处理 URL。You will have to download libcURL 7.21.7 (or some other binary compatible version) and recompile it with IDN support. You will need libidn installed in your system (including development files in the machine where you'll build libcURL).
Alternatively, you can also download the most recent version of libcURL, but you will likely have to recompile PHP (or at least the cURL extension) in that case.
Note that you can also preprocess your URLs using
