  $first=trim($first.fgets($file));
  //echo $first;
  }
    $first1= substr($first,0,8);
    echo $first1." ";
    //mysql_query("insert into test(name) values($first1)");
  //echo $first1;
/*$file1 = fopen("raw_da
  {ta_31_03.txt","rb");  
  while(! feof($file1))
  //echo fgets($file). "<br />";
  */
  //$second=trim($second.fgets($file1));
 
 
    $second1= substr($first,9,7);
    echo $second1 ." ";
 
 
    $third= substr($first,17,5);
    echo $third ." ";
 
    $fourth= substr($first,23,2);
    echo $fourth ." ";
 
    $fifth= substr($first,25,11);
    echo $fifth ." ";
    $sixth= substr($first,50,15);
    echo $sixth ." ";
    $seventh= substr($first,77,2);
    echo $seventh ." ";
 
 
fclose($file);
 
?>
