如何将日语英语字符转换为正常英语字符？ [英] how to transform japanese english character to normal english character?

问题描述

我有一个日语英语字符。
此字符不是正常的英文字符串。

 字符：游戏
  
 
 
 
如何在 php 中将此字符转换为正常英文字符？
解决方案
从每个字符的序数值中减去65248。换句话说：
  $ str =ヴィックサ游戏一些其他文字; 
 $ str = preg_replace_callback（
/ [\x {ff01} -\x {ff5e}] / u，
 function（$ c）{
 //将UTF-8序列转换为序数值
 $ code =（（ord（$ c [0] [0]）& 0xf）<& ]）& 0x3f）<< 6）|（ord（$ c [0] [2]）& 0x3f）; 
 return chr（$ code-0xffe0）; 
} b $ b $ str）; 
  
这将用它们的正常宽度等值替换所有的Fullwidth字符。
 
I have an japanese english character.
This character is not normal english string.
Characters: Ｇａｍｅ
How to transform this character to normal english character in php?
解决方案
Subtract 65248 from the ordinal value of each character. In other words:
$str = "Ｇａｍｅ some other text by ヴィックサ";
$str = preg_replace_callback(
    "/[\x{ff01}-\x{ff5e}]/u",
    function($c) {
        // convert UTF-8 sequence to ordinal value
        $code = ((ord($c[0][0])&0xf)<<12)|((ord($c[0][1])&0x3f)<<6)|(ord($c[0][2])&0x3f);
        return chr($code-0xffe0);
    },
    $str);
This will replace all of the "Fullwidth" characters with their normal width equivalents.
