How can I know a number of uploaded files with PHP?

Question

I have a form with several

input type=\"file\"

tags. How can I know on the server side amount of files uploaded by the user. He can upload

Answer 1

Form:

<form enctype="multipart/form-data" ...>
<input type="file" name="image[]" multiple>

Script:

$c = sizeof($_FILES['image']['name']);

Answer 2

If you are having input upload tags with name like file1, file2 then

if($_FILES['file1']['size'] > 0)
    echo "User uploaded some file for the input named file1"

Now for many files (looking at the output you are having), run a foreach loop like this:-

$cnt=0;
foreach($_FILES as $eachFile)
{
     if($eachFile['size'] > 0)
        $cnt++;
}
echo $cnt." files uploaded";

I am not sure why the similar answer in How can I know a number of uploaded files with PHP? got downvoted? For the '0' ?

Answer 3

You can use the count or sizeof on $_FILES array that contains uploaded file info:

 echo count($_FILES);

Update (Based on comments):

You can do this:

$counter = 0;
foreach($_FILES as $value){
  if (strlen($value['name'])){
    $counter++;
  }
}

echo $counter; // get files count

Answer 4

$_FILES is a global array of files which stores uploaded files.
