Php 警告：copy（）：open_basedir限制生效。文件（）不在允许的路径内：

我不断得到错误：

警告：copy（）：open_basedir限制生效。文件（）不可用 在允许的路径内： 中的（/home/u590953899:/tmp:/var/tmp:/opt/php-5.5/pear） /第22行的home/u590953899/public_html/upload_rename_ac.php

第22行：

if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))

整个代码：

<?php

// Your file name you are uploading 
$file_name = $HTTP_POST_FILES['ufile']['name'];

// random 4 digit to add to our file name 
// some people use date and time in stead of random digit 
$random_digit=rand(0000,9999);

//combine random digit to you file name to create new file name
//use dot (.) to combile these two variables

$new_file_name=$random_digit.$file_name;

//set where you want to store files
//in this example we keep file in folder upload 
//$new_file_name = new upload file name
//for example upload file name cartoon.gif . $path will be upload/cartoon.gif
$path= "/cdn/uploads/".$new_file_name;
if($ufile !=none)
{
if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))
{
echo "Successful<BR/>"; 

//$new_file_name = new file name
//$HTTP_POST_FILES['ufile']['size'] = file size
//$HTTP_POST_FILES['ufile']['type'] = type of file
echo "File Name :".$new_file_name."<BR/>"; 
echo "File Size :".$HTTP_POST_FILES['ufile']['size']."<BR/>"; 
echo "File Type :".$HTTP_POST_FILES['ufile']['type']."<BR/>"; 
}
else
{
echo "Error";
}
}
?>

我在Stack Overflow和google上搜索了一些答案，但什么也没找到。这真的很复杂，那么我该如何解决这个问题呢？

$HTTP\u POST\u FILES

早就被弃用了。您应该使用

$\u文件

和

移动上传的文件（）

。可能重复的请尝试此答案
