EDIT:

here is my code between the 92 and 104 line:

    $handle = fopen ("php://stdin","r");

    $N = $title = fgets($handle, 1024);


    while(!feof($handle))
    {
      if (!$order = fgets($handle)) continue;
      $all_orders[] = explode(',', $order);

    }

    foreach ($all_orders as &$order){

    $order["Order id"]=$order[0];
    unset($order[0]);
    $order["Deal id"]=$order[1];
    unset($order[1]);
    $order["Email address"]=$order[2];
    unset($order[2]);
    $order["Street address"]=$order[3];
    unset($order[3]);
    $order["City"]=$order[4];
    unset($order[4]);
    $order["State"]=$order[5];
    unset($order[5]);
    $order["Zip Code"]=$order[6];
    unset($order[6]);
    $order["Credit Card"]=$order[7];
    unset($order[7]);

    }

print_r($all_orders);

What's in index.php, line 92-104? You're accessing array items that don't exists. — Maerlyn

I have updated my code, there is a snippet from line 92 to 104 of my code, i don't know, but it worked fine hour ago, i didn't changed anything. — Malloc

@Malek Your missing the trim() off the fgets() call - I'm guessing you've got some of those empty items that you were getting a few hours ago... var_dump($all_orders) to confirm ;-) — DaveRandom

In your foreach loop you are accessing array values without checking if they even exist.

PHP gives you a notice every time you're accessing a non-existent index - and in your case, a stack trace (I'm assuming it's XDebug). A notice is not a showstopper mistake, your script simply goes on, and gets another notice, and another, and so forth.

You can check an index' existance with isset($order[$index]).

Also, your seem to be reading CSV data. How about using php's built-in fgetcsv() that already handles many edge cases your code doesn't?

And by the way, your foreach loop is unneccesary, you could be doing that processing in the while loop, after you read a record.

I have already suggested fgetcsv() but the OP seems to have a problem with line endings with this particular file that was causing fgets() to return blank lines for every other record. He is missing a trim() from some code I gave him before which is probably giving him empty records again - see this.
