How to solve the problem of garbled file names obtained by php?

I think many friends will encounter such a problem when developing the upload function of UTF8-encoded PHP. When uploading a file with a Chinese file name, the file name will become garbled. In fact, we You can use the iconv function to re-encode the file name to solve the problem.

The php file uses UTF-8 encoding. If you guessed correctly, APACHE should use GBK for processing. After thinking about this problem, I went to search for relevant tutorials and simply found the iconv function.

Function prototype: string iconv (string in_charset, string out_charset, string str)
Usage example: $content = iconv("GBK", "UTF-8" , $content);
The function of this example is to convert $content from GBK to UTF-8 encoding.

Key code for garbled code problem:
Copy code The code is as follows:

$name=iconv("UTF-8","gb2312", $name);

In addition to solving the problem of Chinese garbled characters in uploaded files, we can also rename the uploaded files.
Example
Copy the code as follows:

$sFileName = “sda.php”;
$sOriginalFileName = $sFileName;
$sExtension = s str($sFileName, (strrpos($sFileName, ‘.’) + 1));//找到扩展名
$sExtension = strtolower($sExtension);
$sFileName = date(“YmdHis”).rand(100, 200).”.”.$sExtension; //这样就是我们的新文件名了，全数字的不会有乱码了哦。

Copy the code as follows:

$filepath=”upload/”;
$name=$filepath.$_FILES[“upfile”][“name”];

$name=$temp[0].”0″.”.”.$temp[1];//主文件名后面加0
}

Copy the code as follows:

//iconv() function is the key

if(move_uploaded_file($_FILES[“upfile”][“tmp_name”],iconv(“UTF-8″,”gb2312”,$name))){//处理…}

My PHP encoding is UTF-8, the reason may be It's because the operating system is GBK!
Note: My server is windows xp, apache, and it is estimated that the xp character set is gbk. Because my PHP code is saved in UTF-8 format, garbled characters will appear when naming the file name, so you can use the iconv() function to convert the original UTF-8 format file name to gbk format.
