问题描述

我从strace获得以下输出，我想使用PHP将其转换为UTF-8:

I have the following output from strace and i want to convert it to UTF-8 using PHP:

R\00f6dhakev\00e4gen 4

推荐答案

发现以下功能有效:

function utf8_urldecode($str) {

  $str = str_replace("\\00", "%u00", $str);

  $str = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($str));

  return html_entity_decode($str,null,'UTF-8');

}
