正确的，PHP包装了ICU的uloc_acceptLanguageFromHTTP而没有传递语言环境列表的能力.总体而言，intl扩展是相对较新的(PHP 5.3+)，我自己也发现了一些错误，这些错误已在下一发行版中迅速修复.

Correct, PHP wraps ICU's uloc_acceptLanguageFromHTTP without the ability to pass your locale list. Overall, intl extension is relatively new (PHP 5.3+) and I did find a couple of bugs myself which were quickly fixed within the next release.

您可以做的是:

• 提交错误/功能请求. 已报告.

• Submit a bug/feature request. There is a similar bug already reported.

Accept-Language格式实际上并不那么复杂，我敢打赌，您可以在20行代码中编写自己的解析器.有关示例，请参见本文.

Accept-Language format is really not that complex, I bet you could write your own parser within 20 lines of code. See this article for an example.
