本文介绍了Php / json：decode utf8？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 29岁程序员，3月因学历无情被辞！ 我存储一个json字符串，其中包含一些（中文？）字符在mysql数据库。 数据库中的示例：I store a json string that contains some (chinese ?) characters in a mysql database.Example of what's in the database:normal.text.\u8bf1\u60d1.rest.of.text 在我的PHP页面上我只是做一个json_decode从mysql接收， t显示正确，它显示像½±è§On my PHP page I just do a json_decode of what I receive from mysql, but it doesn't display right, it shows things like "½±è§�"我试图在我的开始执行SET NAMES'utf8'文件，没有改变任何东西。 我的网页上已经有以下标题：I've tried to execute the "SET NAMES 'utf8'" query at the beginning of my file, didn't change anything.I already have the following header on my webpage:<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />当然所有的php文件都是用UTF-8编码的。And of course all my php files are encoded in UTF-8.你有什么想法如何很好地显示这些\uXXXX字符？Do you have any idea how to display these "\uXXXX" characters nicely?推荐答案 Unicode不是UTF-8！Unicode is not UTF-8!$ echo -en '\x8b\xf1\x60\xd1\x00\n' | iconv -f unicodebig -t utf-8诱惑这是一个奇怪的编码你有。我猜每个字符的正常文本是一个字节长（US-ASCII）？然后你必须提取\u ....序列，转换序列在一个两个字节字符，并转换该字符与 iconv（unicodebig，utf-8，$字符）更改为UTF-8字符（请参见 iconv 在PHP文档中）。这在我身边有效：This is a strange "encoding" you have. I guess each character of the normal text is "one byte" long (US-ASCII)? Then you have to extract the \u.... sequences, convert the sequence in a "two byte" character and convert that character with iconv("unicodebig", "utf-8", $character) to an UTF-8 character (see iconv in the PHP-documentation). This worked on my side:$in = "normal.text.\u8bf1\u60d1.rest.of.text";function ewchar_to_utf8($matches) { $ewchar = $matches[1]; $binwchar = hexdec($ewchar); $wchar = chr(($binwchar >> 8) & 0xFF) . chr(($binwchar) & 0xFF); return iconv("unicodebig", "utf-8", $wchar);}function special_unicode_to_utf8($str) { return preg_replace_callback("/\\\u([[:xdigit:]]{4})/i", "ewchar_to_utf8", $str);}echo special_unicode_to_utf8($in);否则，我们需要更多关于数据库中的字符串如何编码的信息。Otherwise we need more Information on how your string in the database is encoded. 这篇关于Php / json：decode utf8？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
