title: Notice: Undefined offset: 5 when working with an array
body: <p>I want to extract data from an ASC file. But when I try to extract data from it it tells me that it has an undefined offset?</p>
  
  <p>This is the code that I use to extract the data (the error occurs at $data2, $data is fine):</p>
  
  <pre><code>        $File       = $_FILES['file']['tmp_name'];
          $File2      = $_FILES['file2']['tmp_name'];
          $handle     = fopen($File, "r");
          $handle2    = fopen($File2, "r");
          $arrResult  = array();
          $arrResult2 = array();
          fgetcsv($handle);
          fgetcsv($handle);
          fgetcsv($handle);
          fgetcsv($handle);
          fgetcsv($handle);
          fgetcsv($handle);
          while (($data = fgetcsv($handle, 1000, ";")) !== FALSE &amp;&amp; ($data2 = fgetcsv($handle2, 1000, ";")) !== FALSE) {
