Solution to garbled Chinese directory reading by php

Not long ago there was a project involving using php to read file directories. Reading file directories itself is nothing. problem, but when reading the Chinese directory, it turned out to be garbled. I didn’t know what to do for a while. I haven’t encountered this problem for a long time. After some research, I came up with several solutions. I will list them now (will use The method of reading the file directory in php is also attached):

<?php
//要读取的目录
$folder="D:/www";
//打开目录
$fp=opendir($folder);
//阅读目录
while(false!=$file=readdir($fp)){
    //列出所有文件并去掉&#39;.&#39;和&#39;..&#39;
    if($file!=&#39;.&#39; &&$file!=&#39;..&#39;){
    //$file="$folder/$file";
        $file="$file";
        //赋值给数组
        $arr_file[]=$file;
    }
}
//输出结果
if(is_array($arr_file)){
    while(list($key,$value)=each($arr_file)){
        echo "$key=>$value<br>";
    }
}
//关闭目录
closedir($fp);
?>

(1) Make a conversion before output, and add the following code:

$value = iconv("UTF-8","gb2312",$value);  //或者 iconv("gb2312","UTF-8",$value);

(2) All file encodings are Unify to UTF-8 or gb2312
