Question

I have this file upload input in a form:

<input type="file"  multiple name="file[]" />

I have a script which appends this multiple times within the form.

Could I determine which row each file[] array belongs to in php?

<?php 
if(isset($_FILES['file'])=== true){
$files = array ($_FILES['file']);
}
    var_dump($files);

?>

array (size=1)
  0 => 
array (size=5)
  'name' => 
    array (size=5)
      0 => string 'IMG_8502 f 5 .jpg' (length=17)
      1 => string 'IMG_8507 f 5 .jpg' (length=17)
      2 => string 'IMG_8508 f 5 .jpg' (length=17)
      3 => string 'IMG_8529 f 5 .jpg' (length=17)
      4 => string 'IMG_8612 fff 5 .jpg' (length=19)
  'type' => 
    array (size=5)
      0 => string 'image/jpeg' (length=10)
      1 => string 'image/jpeg' (length=10)
      2 => string 'image/jpeg' (length=10)
      3 => string 'image/jpeg' (length=10)
      4 => string 'image/jpeg' (length=10)
  'tmp_name' => 
    array (size=5)
      0 => string 'C:\wamp\tmp\phpE892.tmp' (length=23)
      1 => string 'C:\wamp\tmp\phpE8D1.tmp' (length=23)
      2 => string 'C:\wamp\tmp\phpE911.tmp' (length=23)
      3 => string 'C:\wamp\tmp\phpE950.tmp' (length=23)
      4 => string 'C:\wamp\tmp\phpE99F.tmp' (length=23)
  'error' => 
    array (size=5)
      0 => int 0
      1 => int 0
      2 => int 0
      3 => int 0
      4 => int 0
  'size' => 
    array (size=5)
      0 => int 2776165
      1 => int 2380025
      2 => int 2456713
      3 => int 2585779
      4 => int 1770128

I would like to get each set of files uploaded into their own array. In other words name 0-4 set to be array 0 and then for the next set of files uploaded in the next row to be array 1 and so on. so i can store each set of files with their associated text in the form

<?php
if(isset($_FILES['userfile'])=== true){
  $files = array ($_FILES['userfile']);
  echo  '<pre>';
  print_r($_FILES['userfile']);
  echo  '</pre>';
}
?>


<form action="" method="post" enctype="multipart/form-data">
  Send these files:<br />
    set one:<br>
  <input name="userfile[0][]" type="file" /><br />
  <input name="userfile[0][]" type="file" /><br />
  set two:<br>
  <input name="userfile[1][]" type="file" /><br />
  <input name="userfile[1][]" type="file" /><br />

  <input type="submit" value="Send files" />
</form>
