this script won't output error, it just do nothing. It return correct file only, when I delete some columns. Do you have any idea how to make it faster? This is the code:

/** Error reporting */

/** PHPExcel */
require_once SERVER_ADDRESS.'excel/PHPExcel.php';

/** PHPExcel_IOFactory */
require_once SERVER_ADDRESS.'excel/PHPExcel/IOFactory.php';

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

// Set properties
                             ->setTitle("Office 2007 XLSX Document")
                             ->setSubject("Office 2007 XLSX Document")
                             ->setDescription("Document for Office 2007 XLSX, generated using PHP classes.")
                             ->setKeywords("office 2007 openxml php")
                             ->setCategory("Test result file");

// Create a first sheet

$sharedStyle1 = new PHPExcel_Style();

'fill' => array(
//'type' => PHPExcel_Style_Fill::FILL_SOLID,
//'color'        => array('argb' => 'ffffffff')
'type' => PHPExcel_Style_Fill::FILL_GRADIENT_LINEAR,
'rotation' => 90,
'startcolor' => array('argb' => 'ff76adff'),
'endcolor' => array('argb' => 'ffdeebff')
'font' => array(
'bold' => true,
'color' => array('argb' => 'ff000000')


$sql=mysql_query("SELECT * FROM `turnover_red` ORDER BY `id`");

$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Měsíc');
$objPHPExcel->getActiveSheet()->setCellValue('B1', 'Rok');
$objPHPExcel->getActiveSheet()->setCellValue('C1', 'Region');
$objPHPExcel->getActiveSheet()->setCellValue('D1', 'Odběratel');
$objPHPExcel->getActiveSheet()->setCellValue('E1', 'Produkt');
$objPHPExcel->getActiveSheet()->setCellValue('F1', 'Množství');
$objPHPExcel->getActiveSheet()->setCellValue('G1', 'Cena');
$objPHPExcel->getActiveSheet()->setCellValue('H1', 'Název premixu');
$objPHPExcel->getActiveSheet()->setCellValue('I1', 'Partner');
$objPHPExcel->getActiveSheet()->setCellValue('J1', 'Koncentrace premixu [%]');
$objPHPExcel->getActiveSheet()->setCellValue('K1', 'Množství premixu na tunu [g]');


$variables=Array('id', 'month', 'year', 'region_id', 'vatin', 'product', 'quantity', 'amount', 'premix_name', 'partner', 'premix_concentration', 'premix_quantity');

foreach($variables as $variable) { $$variable=$entry[$variable]; }


$objPHPExcel->getActiveSheet()->setCellValue('A'.$r, $month);
$objPHPExcel->getActiveSheet()->setCellValue('B'.$r, $year);
$objPHPExcel->getActiveSheet()->setCellValue('C'.$r, $region_id);
$objPHPExcel->getActiveSheet()->setCellValue('D'.$r, $vatin_name);
$objPHPExcel->getActiveSheet()->setCellValue('E'.$r, $product_name);
$objPHPExcel->getActiveSheet()->setCellValue('F'.$r, $quantity);
$objPHPExcel->getActiveSheet()->setCellValue('G'.$r, $amount);
$objPHPExcel->getActiveSheet()->setCellValue('H'.$r, $premix_name);
$objPHPExcel->getActiveSheet()->setCellValue('I'.$r, $partner_name);
$objPHPExcel->getActiveSheet()->setCellValue('J'.$r, $premix_concentration);
$objPHPExcel->getActiveSheet()->setCellValue('K'.$r, $premix_quantity);

// Set autofilter

$objPHPExcel->getActiveSheet()->setSharedStyle($sharedStyle1, 'A1:K1');

$objPHPExcel->getActiveSheet()->setTitle('Obraty červené');

// Set active sheet index to the first sheet, so Excel opens this as the first sheet

// Save Excel 2007 file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save(str_replace('.php', '.xlsx', __FILE__));

Have you identified the error? Is this only happening when there are many rows?

Jan 17, 2010 at 5:45 AM

No but i try it now, and it reply with this error:

Fatal error: Allowed memory size of 50331648 bytes exhausted (tried to allocate 262144 bytes) in /data/www/excel/PHPExcel/Worksheet.php on line 993

There is only 1560 rows.

If possible, try to raise memory limit by putting this at the beginning of your script:


ini_set('memory_limit', '128M');
Jan 17, 2010 at 9:18 AM

It doesn't work, but I have default memory_limit 48M, and in error is:

Allowed memory size of 50331648 bytes exhausted (tried to allocate 262144 bytes)

-> it is quite unlogical ... limit 50331648 is much more than 262144 ... Do you have any idea how to repair it?

It is definitely the memory that is exhausted. What version of PHPExcel are you using?

Jan 17, 2010 at 9:42 AM

version 1.7.2, 2010-01-11

Sorry, but there may not be much you can do right now other than increasing memory limit to as high a value as possible and keep yourself updated on when situation with high memory usage changes in PHPExcel.

I have the same problem.

A large excel file (500 rows, but many columns with much data per cell)

No problems arise with using a smaller file.

Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 94 bytes) in /var/www/vhosts/ on line 977

I refer you to my comments in, particul;arly the first paragraph of my response.

put this 

ini_set('memory_limit', '128M');
in the first line of the file, it will work fine.
