上传中文文件名为空
比如 你好.txt 上传到服务器就成了 .txt，文件名部分是空的，不知道为什么。windows系统下文件名不是不允许为空吗?
上传处理代码
<?$upload_path = $_SERVER['DOCUMENT_ROOT']."/upload/";$tmp_file = $_FILES['myfile']['name'];$dest_file = $upload_path.basename($tmp_file);if(move_uploaded_file($_FILES['myfile']['tmp_name'],$dest_file)){ echo "文件已上传至服务器根目录的upload目录下！"; print_r($dest_file);}else{ echo "文件上传时发生了一个错误".$_FILES['myfile']['error'];}?>HTML代码
<html><head><title>upload</title></head><body><form enctype="multipart/form-data" action="upload.php" method="POST">上传此文件:<input name = "myfile" type="file" /><input type="submit" value="提交上传" /></form></body></html>
回复讨论(解决方案)
如果文件名是英文或者数字都是没有问题的。
建议用英文、数字作为文件名，这样移植行更强一些。
如果非要中文名，那就urlencode一下，读取时urldecode过来
gbk字符在utf-8环境中显示为空的正常现象
如果用户上传自己的文件中带有中文怎么办
urlencode和urldecode应该怎么写代码呀，小弟学PHP时间不长，请各位大神指点。
用当前时间戳命名最简单
$dest_file = $upload_path.basename($tmp_file);
改为
$ext=pathinfo($tmp_file,PATHINFO_EXTENSION)$dest_file = $upload_path.time().'.'.$ext;
或者用base64编码，感觉要比urlencode要好。
