Try this

    $objPHPExcel = new PHPExcel();
    $objPHPExcel->getProperties()->setCreator("Maarten Balliauw")
                                 ->setLastModifiedBy("Maarten Balliauw")
                                 ->setTitle("Office 2007 XLSX Test Document")
                                 ->setSubject("Office 2007 XLSX Test Document")
                                 ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")
                                 ->setKeywords("office 2007 openxml php")
                                 ->setCategory("Test result file");
    $objPHPExcel->setActiveSheetIndex(0);
    $sheet = $objPHPExcel->getActiveSheet();
    $sheet->setCellValue('A1', 'No');
    $sheet->setCellValue('B1', 'Job ID');
    $sheet->setCellValue('C1', 'Job completed Date');
    $sheet->setCellValue('D1', 'Job Archived Date');
    $styleArray = array(
        'font' => array(
        'bold' => true
        )
    );
    $sheet->getStyle('A1')->applyFromArray($styleArray);
    $sheet->getStyle('B1')->applyFromArray($styleArray);
    $sheet->getStyle('C1')->applyFromArray($styleArray);

Answer 2

You can try

$objPHPExcel->getActiveSheet()->getStyle(1)->getFont()->setBold(true);

Answer 3

Assuming headers are on the first row of the sheet starting at A1, and you know how many of them there are, this was my solution:

$header = array(
    'Header 1',
    'Header 2'
);

$objPHPExcel = new PHPExcel();
$objPHPExcelSheet = $objPHPExcel->getSheet(0);
$objPHPExcelSheet->fromArray($header, NULL);
$first_letter = PHPExcel_Cell::stringFromColumnIndex(0);
$last_letter = PHPExcel_Cell::stringFromColumnIndex(count($header)-1);
$header_range = "{$first_letter}1:{$last_letter}1";
$objPHPExcelSheet->getStyle($header_range)->getFont()->setBold(true);

Answer 4

Use this:

$sheet->getStyle('A1:'.$sheet->getHighestColumn().'1')->getFont()->setBold(true);
