This is the method I have created for that purpose.

Answer 1

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);
