Aquí hay una respuesta muy reciente a esta pregunta del archivo: 07reader.php

<?php

    exit("Please run 05featuredemo.php first." . EOL);
}

$callStartTime = microtime(true);

$objPHPExcel = PHPExcel_IOFactory::load("05featuredemo.xlsx");

Para leer los datos de microsoft excel 2007 por codeigniter simplemente cree una función auxiliar excel_helper.php y agregue lo siguiente en:

      require_once APPPATH.''libraries/phpexcel/PHPExcel.php'';
      require_once APPPATH.''libraries/phpexcel/PHPExcel/IOFactory.php'';
      in controller add the following code to read spread sheet by active sheet
     //initialize php excel first  
     ob_end_clean();
     //define cachemethod
     $cacheMethod   = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
     $cacheSettings = array(''memoryCacheSize'' => ''20MB'');
     //set php excel settings
     PHPExcel_Settings::setCacheStorageMethod(
            $cacheMethod,$cacheSettings
          );

    $arrayLabel = array("A","B","C","D","E");
    //=== set object reader
    $objectReader = PHPExcel_IOFactory::createReader(''Excel2007'');
    $objectReader->setReadDataOnly(true);

    $objPHPExcel = $objectReader->load("./forms/test.xlsx");
    $objWorksheet = $objPHPExcel->setActiveSheetIndexbyName(''Sheet1'');

    $starting = 1;
    $end      = 3;
    for($i = $starting;$i<=$end; $i++)
    {

       for($j=0;$j<count($arrayLabel);$j++)
       {
           //== display each cell value
           echo $objWorksheet->getCell($arrayLabel[$j].$i)->getValue();
       }
    }
     //or dump data
     $sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);

Answer 3

Usando la biblioteca PHPExcel , el siguiente código funcionará.

require_once dirname(__FILE__) . ''/../Classes/PHPExcel/IOFactory.php'';    
$objReader = PHPExcel_IOFactory::createReader(''Excel2007'');
$objReader->setReadDataOnly(true); //optional

$objPHPExcel = $objReader->load(__DIR__.''/YourExcelFile.xlsx'');
$objWorksheet = $objPHPExcel->getActiveSheet();

$i=1;
foreach ($objWorksheet->getRowIterator() as $row) {

    $column_A_Value = $objPHPExcel->getActiveSheet()->getCell("A$i")->getValue();//column A
    //you can add your own columns B, C, D etc.

    //inset $column_A_Value value in DB query here

    $i++;
}

Answer 4

Usar la biblioteca de PHPExcel para leer un archivo de Excel y transferir los datos a una base de datos

//  Include PHPExcel_IOFactory
include ''PHPExcel/IOFactory.php'';

$inputFileName = ''./sampleData/example1.xls'';

//  Read your Excel workbook
try {
    $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
    $objReader = PHPExcel_IOFactory::createReader($inputFileType);
    $objPHPExcel = $objReader->load($inputFileName);
} catch(Exception $e) {
    die(''Error loading file "''.pathinfo($inputFileName,PATHINFO_BASENAME).''": ''.$e->getMessage());
}

//  Get worksheet dimensions
$sheet = $objPHPExcel->getSheet(0); 
$highestRow = $sheet->getHighestRow(); 
$highestColumn = $sheet->getHighestColumn();

//  Loop through each row of the worksheet in turn
for ($row = 1; $row <= $highestRow; $row++){ 
    //  Read a row of data into an array
    $rowData = $sheet->rangeToArray(''A'' . $row . '':'' . $highestColumn . $row,
                                    NULL,
                                    TRUE,
                                    FALSE);
    //  Insert row data array into your database of choice here
}

Cualquier cosa más se vuelve muy dependiente de su base de datos, y cómo quiere que los datos estén estructurados en ella

      if($query)
       {
        // try to export to excel the whole data ---

        ini_set(''memory_limit'', ''3500M'');
        $cacheMethod   = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
        $cacheSettings = array(''memoryCacheSize'' => ''800MB'');
        //set php excel settings
        PHPExcel_Settings::setCacheStorageMethod(
                $cacheMethod,$cacheSettings
              );


        $objPHPExcel->getProperties()->setTitle("export")->setDescription("none");

        $objPHPExcel->setActiveSheetIndex(0);

        // Field names in the first row
        $fields = $query->list_fields();
        $col = 0;
        foreach ($fields as $field)
        {
            $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
            $col++;
        }

        // Fetching the table data
        $row = 2;
        foreach($query->result() as $data)
        {
            $col = 0;
            foreach ($fields as $field)
            {
                $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $data->$field);
                $col++;
            }

            $row++;
        }

        $objPHPExcel->setActiveSheetIndex(0);
        //redirect to cleint browser
        header(''Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'');
        header(''Content-Disposition: attachment;filename=Provinces.xlsx'');
        header(''Cache-Control: max-age=0'');

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, ''Excel2007'');
        $objWriter->save(''php://output'');
     }
