在下面的Android和PHP代码中，我尝试将手机中的小文本文件上传到00webhost server。
该文件目前根本没有上传，代码中是否有syntax errors？
我不知道在file/folder path中上传文件的00webhost是否正确？它是public_html吗？
请注意，在下面的android代码中：
String urlServer = "serverpath.../handle_upload.php";
package com.example.fileservertest;
显然不是真正的网址，我不想公开展示它。

outputStream.flush();
outputStream.close();

}
对应PHP脚本：
<?php
$target_path = ".\";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path))
{
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
}
else
{
echo "There was an error uploading the file, please try again!";
}
？取代;
