上传文件时，文件大小统计失败

Question

I'm facing strange problem right now - "filesize(): stat failed for C:\xampp\tmp\php7A38.tmp" exception. The problem occurs when I'm uploading files in my application built with PHP (Laravel).

Before I'm uploading the files onto the server I'm checking size of files like this (this works very well):

for ($i = 0; $i < $filesLength; $i++) {
   if(filesize($request['files'][$i]) < 1572865) {
      $file = $request['files'][$i];
      $filename = $imageNumber.'.'.$request['files'][$i]->extension();
      $file = $file->move(public_path().'/app/newsimages/'.$element->id.'/', $filename);
   }
}

If I do it like that everything works very well. But the problem is that I have to put this loop in another loop, like this:

foreach($somelement as $element) {
  for ($i = 0; $i < $filesLength; $i++) {
    if(filesize($request['files'][$i]) < 1572865) {
      $file = $request['files'][$i];
      $filename = $imageNumber.'.'.$request['files'][$i]->extension();
      $file = $file->move(public_path().'/app/newsimages/'.$element->id.'/', $filename);
    }
  }
}

In addition to that it crashes at the second loop of the foreach loop.

Maybe you have some idea what's wrong in here?

Answer 1

I think this is obvious, in inner loop you move the file, so when you go to next iteration of outer loop file is not there, so for example if you once move the file:

$request['files'][0]

it's not possible to execute:

filesize($request['files'][0])

because this file was moved - it doesn't exist any more.
