Php conditional file upload issue

Question

In my program I allow the user to upload 0 to 10 pics.

But In my php script when I check if a file is upload even if there is no file the script is read.

So even if the user upload just a file ("media-pic1") All the other script are read ( for example if(isset($_FILES['media-pic2'])) is true)

The html:

<input type="file" id="upload-pic1" name="media-pic1" class="hidden">

<input type="file" id="upload-pic2" name="media-pic2" class="hidden">

<input type="file" id="upload-pic3" name="media-pic3" class="hidden">

<input type="file" id="upload-pic4" name="media-pic4" class="hidden">

etc

The php:

if(isset($_FILES['media-pic1']))
{....}

if(isset($_FILES['media-pic2']))
{....}

if(isset($_FILES['media-pic3']))
{....}

...

if(isset($_FILES['media-pic10']))
{....}

PLease help

Use for loop for the solution . For displaying html, use following code.

<?php 
    for ($x = 0; $x <= 10; $x++) {
        echo '<input type="file" id="upload-pic'.$x.'" name="media-pic'.$x.'" class="hidden">';

    } 
?>

When uploading in php,

<?php 
    for($x=0;$x<=10;$x++){
        if(is_uploaded_file($_FILES['media-pic'.$x]['tmp_name']){
            //perform required operation.
        }
    }
?>
