You need to add the key to the array

<input type="checkbox" name="check[0]"  />

and

var num = 1;
$("#add-file-field").click(function(){
    $("#text").append("<div class='added-field'><input type='checkbox' name='check["+num+"]' />Never Expired</div>");
    num++;
});

Checkboxes that are not checked are not sent to the server by the browser, and hence are not in the $_POST['check'] array. This is why THERE IS A VALUE always comes first.

You can see this for a guide in the future...

http://www.html-form-guide.com/php-form/php-form-checkbox.html

Your problem is , you just check that is is set. You must check thier value..

Fix your html form like this

    <input type="checkbox" name="check" value="1"> checkbox1</input>
   "----do the same---------------------------"2""---------2------->"//do this until you get your five checkbox

Then on php

  <?php

    include('config.php');

    if(isset($_POST['submit']))
    {
      for($x = 0;$x <= 5;$x++)
       {
         if($_POST['check']==strval($x))
          {
            echo "THERE IS A VALUE<br>";
          }
         else{
            echo "EMPTY<br>";
          }
       }
    }
 ?>

Hope it works

PS. If anyone see errors please edit it.

Hope this is work add

<input type="checkbox" name="check[0]"  />

then edit this

var x = 1;
$("#add-file-field").click(function(){
$("#text").append("<div class='added-field'><input type='checkbox' name='check["+x+"]'     />Never Expired</div>");
x++;
});

then simple php code

 if(isset($_POST['submit']))
{
   // $x = cout($_POST['check']);
    for($x = 0;$x <= 5;$x++)
    {
        if(strlen($_POST['check'][$x])>1)
        {
            echo "THERE IS A VALUE<br>";
        }
        else{
            echo "EMPTY<br>";
        }
    }
}

thanks
