För att importera en CSV-fil till ett PHPExcel-objekt
$inputFileType = 'CSV';
$inputFileName = 'testFile.csv';
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
För att exportera en CSV-fil från ett PHPExcel-objekt
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
$objWriter->save('testExportFile.csv');

Så här läser du igenom raderna och cellerna:
$worksheet = $objPHPExcel->getActiveSheet();
foreach ($worksheet->getRowIterator() as $row) {
echo 'Row number: ' . $row->getRowIndex() . "\r\n";
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
echo 'Cell: ' . $cell->getCoordinate() . ' - ' . $cell->getValue() . "\r\n";
}
}
}
Hur man skriver till ett PHPExcel-objekt:Du säger inte var din data kommer ifrån:så här gör du det från en MySQL-fråga
$query = sprintf("SELECT firstname, lastname, age, date_of_birth, salary FROM employees WHERE firstname='%s' AND lastname='%s'",
mysql_real_escape_string($firstname),
mysql_real_escape_string($lastname));
$result = mysql_query($query);
$row = 1;
$objPHPExcel->getActiveSheet()->setCellValue('A'.$row, 'First Name')
->setCellValue('B'.$row, 'Last Name')
->setCellValue('C'.$row, 'Age')
->setCellValue('D'.$row, 'Date of birth')
->setCellValue('E'.$row, 'Salary');
$row++;
while ($rec = mysql_fetch_assoc($result)) {
$objPHPExcel->getActiveSheet()->setCellValue('A'.$row, $rec['firstname'])
->setCellValue('B'.$row, $rec['lastname'])
->setCellValue('C'.$row, $rec['age'])
->setCellValue('D'.$row, PHPExcel_Shared_Date::stringToExcel($rec['date_of_birth']))
->setCellValue('E'.$row, $rec['salary']);
$objPHPExcel->getActiveSheet()->getStyle('D'.$row)->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_XLSX15);
$objPHPExcel->getActiveSheet()->getStyle('E'.$row)->getNumberFormat()->setFormatCode('£#,##0.00');
$row++;
}
