PHP复制或移动上传的文件 - 什么也没有发生，但没有错误

我没有得到任何错误，但我没有收到文件复制或者：PHP复制或移动上传的文件 - 什么也没有发生，但没有错误

$upload_folder = "uploads/"; 

$name_of_uploaded_file = basename($_FILES['uploaded_file']['name']); 

$prefix = date("YmdHis"); 
$path_of_uploaded_file = "$upload_folder$prefix-$name_of_uploaded_file"; 
$tmp_path = $_FILES["uploaded_file"]["tmp_name"]; 

if(is_uploaded_file($tmp_path)) 
{ 
    if(!copy($tmp_path,$path_of_uploaded_file)) 
    { 
    $errors .= '\n error while copying the uploaded file'; 
    } 
} 

echo $path_of_uploaded_file; 
echo $name_of_uploaded_file; 
echo $errors;

这工作正常在Windows开发环境，但是部署到Linux Web服务器就是这样做的。我们最初得到一个复制错误，然后我们添加了上传目录的权限。现在我们什么都没有。

我也试过这与move_uploaded_file，没有错误，但在上传目录中没有结果文件。

您完全确定该文件的路径是正确的？ –

@Evan Mulawski我们对它进行了回应（它在Windows上工作） - 它显示完整路径和基本名称都很好。我们也回应了$ tmp_path，这看起来很好（但我们似乎没有足够快的速度看到文件出现 - 我认为它的寿命很短）。如果该文件不在tmp中，我们应该会看到一个复制错误，我想呢？ –

你的窗体中是否有'MAX_FILE_SIZE'输入？你可能会这样做，所以尝试将值设置为'0'（零）。 –

也许你可以添加一个检查，如果is_uploaded_file返回true。

if(is_uploaded_file($tmp_path)) 
{ 
    if(!copy($tmp_path,$path_of_uploaded_file)) 
    { 
    $errors .= '\n error while copying the uploaded file'; 
    } 
} else { 
    $errors .= '\n error while uploading file'; // maybe upload_max_filesize exceeded 
// try to get the specific error 

switch($_FILES['uploaded_file']['error']){ 
    case 0: //no error; possible file attack! 
     echo "There was a problem with your upload."; 
     break; 
    case 1: //uploaded file exceeds the upload_max_filesize directive in php.ini 
     echo "The file you are trying to upload is too big."; 
     break; 
    case 2: //uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the html form 
     echo "The file you are trying to upload is too big."; 
     break; 
    case 3: //uploaded file was only partially uploaded 
     echo "The file you are trying upload was only partially uploaded."; 
     break; 
    case 4: //no file was uploaded 
     echo "You must select an image for upload."; 
     break; 
    default: //a default error, just in case! :) 
     echo "There was a problem with your upload."; 
     break; 

}

也许你的upload_max_filesize超标，或者有其他的服务器设置，不允许上传。

'$ _FILES ['uploaded_file'] ['error']'为0，'is_uploaded_file（$ tmp_path）'为真 –

好的，但现在我们知道了至少可以确定上传本身工作。我想你已经试图转储$ _FILES变量，$ tmp_path变量和$ path_of_uploaded_file变量，并检查文件系统中是否有文件？我猜想上传的文件的位置可能存在问题，例如，你是否尝试在场名上调用realpath函数并检查它们是否正确？ –

转储的名称，类型，tmp_name，错误，大小 - 一切看起来不错。让我们看看实际路径给出了什么。（不用说，PHP对我而言是新事物）。 –

$upload_folder = "uploads/"; 
$path_of_uploaded_file = "$upload_folder$prefix-$name_of_uploaded_file";

让你$path_of_uploaded_file是

$path_of_uploaded_file = "$upload_folder/$prefix-$name_of_uploaded_file";
