PHP上传文件名乱码，win环境。

Question

服务器是win环境，上传中文文件名会乱码，网上说要加一句编码转换，请问怎么加，麻烦直接帮我加一下可以吗？我是美工，这个对我有点难。谢谢

<?php

// If you want to ignore the uploaded files,
// set $demo_mode to true;

$demo_mode = false;
$upload_dir = 'uploads/';
$allowed_ext = array('wer');

if(strtolower($_SERVER['REQUEST_METHOD']) != 'post'){
exit_status('Error! Wrong HTTP method!');
}

if(array_key_exists('pic',$_FILES) && $_FILES['pic']['error'] == 0 ){

$pic = $_FILES['pic'];

if($demo_mode){

// File uploads are ignored. We only log them.

$line = implode(' ', array( date('r'), $_SERVER['REMOTE_ADDR'], $pic['size'], $pic['name']));
file_put_contents('log.txt', $line.PHP_EOL, FILE_APPEND);

exit_status('Uploads are ignored in demo mode.');
}

// Move the uploaded file from the temporary
// directory to the uploads folder:

if(move_uploaded_file($pic['tmp_name'], $upload_dir.$pic['name']))

{
exit_status('File was uploaded successfuly!');
}

}

exit_status('Something went wrong with your upload!');

// Helper functions

function exit_status($str){
echo json_encode(array('status'=>$str));
exit;
}

function get_extension($file_name){
$ext = explode('.', $file_name);
$ext = array_pop($ext);
return strtolower($ext);
}
?>

只要不乱码，重命名也可以。

Answer 1

if(move_uploaded_file($pic['tmp_name'], $upload_dir.$pic['name']))
改为
if(move_uploaded_file($pic['tmp_name'], iconv("UTF-8","GBK",$upload_dir.$pic['name'])))

追问

试了一下不可以哦，还是乱码，是WIN环境，是这个原因吗？我看网上说WIN，和CentOS写法不一样吗？
