When I create/open a File to write, only could be written in the File when there is one Byte in the File.

Can you Help me ?


while ($row = mysql_fetch_row($result)) {

   $fname="export.dat";

        if ($fp = fopen($fname, "a+")) {
             for ($i=0;$i<=13;$i++) {
             $data[$i]=("$row[$i],");
             fputs($fp,$data[$i]);
          
             }
             fclose($fp);
             }
}
