I am getting Undefined notice. Could anybody help out. Below are code
-------------------------------
<?PHP set_time_limit(0); require("./dbconfig/db_connect.php");
//////////////////////////////////////SEARCH BARCODE TAG//////////////////////

$lines = glob("D:/nusphere/apache/htdocs/Msafe/phonoApp/final/ftp_downloaded/*.txt");
for($i=0;$i<sizeof($lines);$i++){ $fp=fopen($lines[$i],"r+") or die("error opening");
$file_content =fread($fp,filesize($lines[$i]));
fclose($fp);
$arrContent=explode("\n",$file_content);
//print_r($arrContent);
//check to see if this is your search string
SizeOf($arrContent);
$barCodeinfo="";
$trackOrder=0;
$updateRecordCount=0; for($j=0;$j<sizeof($arrContent);$j++){ $arrData=explode(";",$arrContent[$j]);

$barCode=$arrData[0];
$SoundLink=$arrData[3];
$Supplier_TrackID=$arrData[1];

if($barCode<>$barCodeinfo){ $barCodeinfo=$barCode;
$trackOrder=0; } else $trackOrder++;
// echo "SELECT tbltracks.* FROM tbltracks,tblcollection WHERE tblcollection.barcode='".str_replace("'","''",trim($barCode))."' ORDER BY tbltracks.ID Limit ".($trackOrder).",1"."</br>"; // echo "UPDATE tbltracks SET Sound_Links='".($SoundLink)."' WHERE ID ='{$row['ID']}'"."</br>"; $rec = mysql_query("SELECT tbltracks.* FROM tbltracks,tblcollection WHERE tbltracks.FT_SuplProdID=tblcollection.suplprodid and tblcollection.barcode='".str_replace("'","''",trim($barCode))."' ORDER BY tbltracks.ID Limit ".($trackOrder).",1"); $updateRecordCount++; //OK if ($row = mysql_fetch_array($rec)){ mysql_query("UPDATE tbltracks SET Sound_Links='".($SoundLink)."' WHERE ID ='{$row['ID']}'"); echo "Updating ......................."; } else{}; } if($updateRecordCount%50) sleep(1); } ?>
