任何人都可以帮助我吗？我怎么能得到UCS2/HexEncoded字符
比如'你好'会返回"00480065006C006C006F"
这是HexEncoded值:
0048 = H 0065 = e 006C = 006C = 1006F = o*
也在阿拉伯语(!مرحباعالم)将返回06450631062d0628064b06270020063906270644064500200021
我如何在PHP中获得编码的UCS2？
mb_convert_encoding($ str,'UCS-2','auto')可正常转换字符串,但您必须做额外的工作才能在浏览器中获得正确的输出.
您需要更改输出的字符集以匹配UCS-2,以便能够使用echo将其输出到页面.此外,您可能还需要通过标头中的元标记设置Content-Type .
我在下面的unicode变体中包含了三个例子:UCS-2,UTF-16和UTF-8; 因为并非所有这些都在我没有调整Internet Explorer的情况下工作.您可能需要以UTF-8存储PHP文件才能获得正确的结果.此外,我在Windows的英文版本,所以我不能以适当的RTL格式输入您的阿拉伯字符串.如果你的字符串在这里乱码,我很抱歉.我向您保证,如果您在我的评论中注明的位置更换它,您将获得正确的结果.最后,您可能无法在Internet Explorer中查看UCS-2和UTF-16-当通过缓存重新加载输出时似乎有些奇怪.但是,FireFox 3.5.5适用于所有三种编码.如果您对制作应用程序非常认真,我强烈建议您考虑使用UTF-8而不是UCS-2.
FireFox 3.5.5(好吧,但FireFox在我的测试中说它是UTF-16BE.)
Internet Explorer 7.0(不是.没有正确检测/转换阿拉伯语.)
