PHPExcel: Using a MySQLi query on '01simple-download-xls.php' example

Question

Would anyone know of a good working example of someone taking the "01simple-download-xls.php" of PHPExcel and modifying it to work with a MySQLi query? I've been having some trouble finding a good working example.

I'd like to leave everything in the example intact and just replace this one section of code (below) with a MySQLi query.

It looks like I could just loop through the query and dump the setCellValue (I think). I've been trying to find a more elegant solution where (without knowing the number of columns involved) the code could work for any query without modifications.

So, I'd like to just replace this one piece of the example:

// Add some data
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', 'Hello')
            ->setCellValue('B2', 'world!')
            ->setCellValue('C1', 'Hello')
            ->setCellValue('D2', 'world!');

// Miscellaneous glyphs, UTF-8
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A4', 'Miscellaneous glyphs')
            ->setCellValue('A5', 'éàèùâêîôûëïüÿäöüç');

This is the full example file included in the PHPExcel samples (01simple-download-xls.php):

Answer 1

Download PHPExcel here and try the below code.

$sql = mysqli_query($conn, "SELECT id FROM invoice_product WHERE model_name = '$mname' && model_no = '$mno' ORDER BY color");
$a=0;
while ($result = mysqli_fetch_array($sql))
{
    $id_array[$a] = $result[id];
    $a++;
}

$sql2 = mysqli_query($conn, "SELECT * FROM invoice_imei WHERE invoice_product_id IN (".implode(',',$id_array).")");

$setExcelName = "IMEI"; 

require_once '../PHPExcel/Classes/PHPExcel/IOFactory.php';
require_once '../PHPExcel/Classes/PHPExcel.php';

// Create new PHPExcel object
$objPHPExcel = new PHPExcel(); 

//setting column heading
$objPHPExcel->getActiveSheet()->setCellValue('A1',"Model Name"); 
$objPHPExcel->getActiveSheet()->setCellValue('B1',"Model No."); 
$objPHPExcel->getActiveSheet()->setCellValue('C1',"Color"); 
$objPHPExcel->getActiveSheet()->setCellValue('D1',"IMEI"); 
$objPHPExcel->getActiveSheet()->setCellValue('E1',"Status"); 

//setting column body
$i=2; //starting from row 2 bcz row 1 set to header
while ($result2 = mysqli_fetch_array($sql2)) {
    $sql3 = mysqli_query($conn, "SELECT color FROM invoice_product WHERE id = '$result2[invoice_product_id]'"); 
    $result3 = mysqli_fetch_assoc($sql3);

    $objPHPExcel->getActiveSheet()->setCellValue('A'.$i,$mname);
    $objPHPExcel->getActiveSheet()->setCellValue('B'.$i,$mno);
    $objPHPExcel->getActiveSheet()->setCellValue('C'.$i,$result3[color]);
    $objPHPExcel->getActiveSheet()->setCellValue('D'.$i,$result2[imei]);
    if ($result2[status] == 0) { 
        $objPHPExcel->getActiveSheet()->setCellValue('E'.$i,'Not Used');
    } else {
        $objPHPExcel->getActiveSheet()->setCellValue('E'.$i,'Used');
    }
    $i++;
}
// Redirect output to a client’s web browser (Excel5)
header('Content-type: application/xlsx');
header('Content-Disposition: attachment;filename="IMEI.xls"');
header('Cache-Control: max-age=0');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

$objWriter->save('php://output');
exit;

Answer 2

You can take advantage of the worksheet's fromArray() method to set a row of cells from an array as a single call, which will work regardless of how many values there are in the array:

$row=2;
while ($result = mysqli_fetch_row($queryResultSet)) {
    $objPHPExcel->getActiveSheet()
        ->fromArray($result, null, 'A'.$row++);
}
