Using arrays when uploading a file

1

i’m trying to upload multiple files using arrays…which works fine…but i’m specifically trying to define a variable based on the number of the array.

here’s my code to see what i mean:

    if ($_POST['action'] == 'editmultiple')
        $files = array();
    foreach ($_FILES['photosnews'] as $k => $l) {    
        foreach ($l as $i => $v) {
            if (!array_key_exists($i, $files)) 
                $files[$i] = array();
            $files[$i][$k] = $v;
              ##### THIS IS WHERE I'M HAVING TROUBLE ####
            if ($_FILES['photosnews'] == 1) { 
                $vartest = "this is one";
            } else {
                $vartest = "this is not one";
            }
              #################################
        }
    }

so my logic is that each file has a specific array number starting from 0…when the file has an array number of 1, i want to set a variable to something…and then if it’s 2, i want it to set to something different…i’m just not sure what to put in that if statement so that it knows what array number does what. i’m thinking maybe a for statement would be better…but i’m not sure how to get it work with what i have so far.

here’s part of the form too if needed:

<input name="photosnews[]" type="file" class="input" size="10" accept="image/gif, image/jpeg, image/jpg" >
<input type="hidden" name="action" value="editmultiple" />

any help would be greaty appreciated!
