php What should I do if the name of the new file is garbled?

Under Windows, when PHP calls the mkdir(), file_put_contents(), and fopen() functions to create a directory or document name with Chinese characters, garbled characters appear.

Cause

After consulting the information, this is related to the system character set.

• windows (Simplified Chinese), the default character set is: gbk

• windows (Traditional Chinese), the default character set is: big5

• linux, the default character set is: utf-8

Solution

Use iconv or mb_convert_encoding function Convert character encoding.

//将字符串 str 从 in_charset 转换编码到 out_charset。
string iconv ( string $in_charset , string $out_charset , string $str )
//将 string 类型 str 的字符编码从可选的 from_encoding 转换到 to_encoding。
string mb_convert_encoding ( string $str , string $to_encoding [, mixed $from_encoding = mb_internal_encoding() ] )

Convert encoding according to system settings, the method is as follows:

<?php
/**
 * 转换字符编码
 * @param $string
 * @return string
 */
function convertEncoding($string){
    //根据系统进行配置
    $encode = stristr(PHP_OS, &#39;WIN&#39;) ? &#39;GBK&#39; : &#39;UTF-8&#39;;
    $string = iconv(&#39;UTF-8&#39;, $encode, $string);
    //$string = mb_convert_encoding($string, $encode, &#39;UTF-8&#39;);
    return $string;
}

Garbled code example

<?php
#示例1
$dir = __DIR__ . &#39;/中英文目录Test1&#39;;
mkdir($dir); 
//目录名：涓嫳鏂囩洰褰昑est1
#示例2
$fileName = __DIR__ . &#39;/中英文档名Test2.txt&#39;;
file_put_contents($fileName, &#39;文件内容Test2&#39;);
//文件名：涓嫳鏂囨。鍚峊est2.txt
//文件内容：文件内容Test2
#示例3
$fileName = __DIR__ . &#39;/中英文档名Test3.txt&#39;;
$fp = fopen($fileName, &#39;w&#39;);
fwrite($fp, &#39;文件内容Test3&#39;);
fclose($fp);
//文件名：涓嫳鏂囨。鍚峊est3.txt
//文件内容：文件内容Test3
?>

Solution example

<?php
#示例1
$dir = __DIR__ . &#39;/中英文目录Test1&#39;;
$dir = convertEncoding($dir);
mkdir($dir); 
//目录名：中英文目录Test1
#示例2
$fileName = __DIR__ . &#39;/中英文档名Test2.txt&#39;;
$fileName = convertEncoding($fileName);
file_put_contents($fileName, &#39;文件内容Test2&#39;);
//文件名：中英文档名Test2.txt
//文件内容：文件内容Test2
#示例3
$fileName = __DIR__ . &#39;/中英文档名Test3.txt&#39;;
$fileName = convertEncoding($fileName);
$fp = fopen($fileName, &#39;w&#39;);
fwrite($fp, &#39;文件内容Test3&#39;);
fclose($fp);
//文件名：中英文档名Test3.txt
//文件内容：文件内容Test3
/**
 * 转换字符编码
 * @param $string
 * @return string
 */
function convertEncoding($string){
    //根据系统进行配置
    $encode = stristr(PHP_OS, &#39;WIN&#39;) ? &#39;GBK&#39; : &#39;UTF-8&#39;;
    $string = iconv(&#39;UTF-8&#39;, $encode, $string);
    //$string = mb_convert_encoding($string, $encode, &#39;UTF-8&#39;);
    return $string;
}
