How to import excel data into database using PHP excel library

Question

I am trying to import excel data into database using PHP excel Library.It is working for small amount of data.For large data (30000 rows) it is not working.It is taking much time.
here is my code

$fileName = $_FILES["production"]["tmp_name"];
$objPHPExcel = PHPExcel_IOFactory::load($fileName);
$phpspreadsheet = $objPHPExcel->getSheet(0);
                 
                $total_data = $phpspreadsheet->getHighestRow();
                     //echo $chunkSize;
                    // exit;
                $highest_column = $phpspreadsheet->getHighestColumn();
for ($row = 2 ; $row <= $total_data; $row++) {
                   $productionDataAll = $phpspreadsheet-> rangeToArray ('A' . $row . ':' . $highest_column . $row, NULL, TRUE, FALSE);
                        
                         $line=htmlentities($productionDataAll[0][0]);
                         $workedorder=htmlentities($productionDataAll[0][1]);
                         $modelnumber=htmlentities($productionDataAll[0][2]);
                         $revision=htmlentities($productionDataAll[0][3]);
                         if(!empty($productionDataAll[0][4])){
                         $serialnumber=htmlentities($productionDataAll[0][4]);
                         }
                         else{
                           $serialnumber='';
                         }
                         $lpn=htmlentities($productionDataAll[0][5]);
                         $shift=htmlentities($productionDataAll[0][6]);
                         $datecreated=htmlentities($productionDataAll[0][7]);
                         $datecompleted=htmlentities($productionDataAll[0][8]);
                         $repairflag=htmlentities($productionDataAll[0][9]);
                         $date=date("Y-m-d", strtotime( '-1 days' ) );
                         $skeydate=date("Ymd", strtotime( '-1 days' ) );
                           $skey=$skeydate.$line;
  $importproduction=importproduction($mysql_connectionLinkLocal,$line,$workedorder,$modelnumber,$revision,$serialnumber,$lpn,$shift,$repairflag,$date,$skey,$datecreated,$datecompleted); // insert function
            
                  }

above code is reading sheet data one by one and inserting into database. How to read the sheet data by 100 (chunck)? How to reduce the loading time?I am getting page unresponsive

Answer 1

Try https://github.com/aVadim483/fast-excel-reader

It can read excel data very quickly and with minimal memory usage (but XLSX format only). There is example with reading of 100K spreadsheet in demo folder
