PHP+MYSQL 出现乱码的解决方法
在PHP中,\\u0026代表Unicode编码中的&符号。当使用该编码时,可能会导致字符显示为乱码。要解决这个问题,可以使用封装方法decodeUnicode来将Unicode编码转换为UTF-8编码。
首先,需要在PHP文件中指定输出的编码为UTF-8,可以通过以下方式实现:
header("Content-Type: text/html; charset=utf-8");
然后,可以使用封装方法decodeUnicode来解析URL中的Unicode编码。下面是一个示例代码:
function decodeUnicode($str) {
return preg_replace_callback('/\\\\u([0-9a-f]{4})/i', function ($matches) {
return mb_convert_encoding(pack("H*", $matches), "UTF-8", "UCS-2BE");
}, $str);
}
接下来,可以将包含Unicode编码的URL传入decodeUnicode方法进行解码:
$url = 'https:\u002F\u002Ftx2.a.yximgs.com\u002Fupic\u002F2020\u002F06\u002F17\u002F11\u002FBMjAyMDA2MTcxMTMyMjhfODczNzMyOTA2XzMwNjM4MTQ0MzIyXzFfMw==_Bad802661b6047bb880b03afc84f3d1aa.jpg?di=7b7d5c05&bp=10004';
$url_new = decodeUnicode($url);
最后,输出解码后的URL:
echo $url_new;
这样就可以正确地显示包含Unicode编码的URL,避免乱码问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
