本文介绍了如何解码Unicode转义序列,如“\\\”适当的UTF-8编码字符?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在PHP中有一个函数可以解码Unicode转义序列,如 \\\í
到í
和所有其他类似的事件? 我发现类似的问题,但似乎不起作用。
解决方案
尝试这样:
$ str = preg_replace_callback('/ \\\\ 0-9a-fA-F] {4})/',function($ match){
return mb_convert_encoding(pack('H *',$ match [1]),'UTF-8' -2BE');
},$ str);
如果是基于UTF-16的C / C ++ / Java / Json样式:
$ str = preg_replace_callback('/ \\\\u([0-9a-fA-F] {4}) /',function($ match){
return mb_convert_encoding(pack('H *',$ match [1]),'UTF-8','UTF-16BE');
},$ STR);
Is there a function in PHP that can decode Unicode escape sequences like "\u00ed
" to "í
" and all other similar occurrences?
I found similar question here but is doesn't seem to work.
解决方案
Try this:
$str = preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/', function ($match) {
return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');
}, $str);
In case it's UTF-16 based C/C++/Java/Json-style:
$str = preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/', function ($match) {
return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UTF-16BE');
}, $str);
