By writing

<tr><?echo "<td><input type=\"checkbox\" name=\"checkbox[]\" id=\"checkbox[]\"  value=\"".$row['id']."\" /></td>";?>

you have designed a form which returns an array of values with each value corresponding to a checkbox that has been “checked”.

In this example the POST variable that points to this array will be $_POST[‘checkbox’]. Since you have set the value of each checkbox as $row[‘id’], each element in the checkbox array will have the ‘id’ value corresponding to each checkbox that you have checked.

You can check out these values like this:

foreach($_POST['checkbox'] as $value)
{ 
  echo $value;
}

or simply by saying:

echo var_dump($_POST['checkbox']);

Hope this makes it clear. 🙂
