Undefined offset: 624

The problem is when i am adding the more than 624 stickers.

The code works fine when the stickers are less than 624. it seems to not allow for more stickers.

I seem to be having a strange error that i cant fix.

the error i keep getting is: Undefined offset: 624

this is what i have:

php: 

 //product names
        for ($x = 0; $x < $counter; $x++) {

            $product[] = $_POST["product_name"][$x];
            $product_price[] = preg_replace('/\s+/', '', $_POST["product_price"][$x]);
            $product_barcode[] = preg_replace('/\s+/', '', $_POST["product_barcode"][$x]);
            $product_stickers[] = preg_replace('/\s+/', '', $_POST["product_stickers"][$x]);
            $vendor_code[] = $result = $this->getUsername($user_id, $x);

        }

 $result = array();
                $values = array($product, $product_price, $product_barcode, $vendor_code, $product_stickers);
                //$values = array($product, $product_price, $product_barcode, $vendor_code);

                foreach ($products as $index => $key) {
                    $t = array();
                    foreach ($values as $value) {

                        $t[] = $value[$index];

                    }

                    $result[$key] = $t;
                }

                $products_json = json_encode($result);

html: 

    @for($x = 0; $x <= 650; $x++)

    <tr>
    <td><input type="text" name="product_name[]" class="product_name"
        value="{{$x}}"></td>

    <td><input type="text" name="product_price[]" class="product_price"
         value="{{$x}}"></td>

    <td><input type="text" name="product_barcode[]"  

        class="product_barcode"
        value="{{$x}}"></td>

   <td><input type="text" name="product_stickers[]"  

       class="product_stickers"
       value="{{$x}}"></td>

   <td><a role="button" style="color:#fff" class="delRowBtn btn btn-  

    warning">Remove</a>
   </td>

   </tr>

    @endfor

im not sure why it is not working for adding more than 624 stickers please help!

It is may be you are posting more data then it's allowed in php.ini eg. increase post_max_size and max_input_vars

This will resolve the issue I guess.

Always check existence of variable before use, specially when it is in dynamic array. Possible issue: 1. index start from 1 and in loop starts from 0 2. Object fetched before it was assign. However,

$product[] = $_POST["product_name"][$x] ?? null;

or

$product[] = (!empty($_POST["product_name"][$x])) ? $_POST["product_name"][$x] : null;

put conditions before use. all places where dynamic key is generated for array to rid-off errors.
