PHPExcel Make first row bold

Question

I am trying to make cells in first row are bold.

This is the method I have created for that purpose.

function ExportToExcel($tittles,$excel_name)
 {
         


        

Answer 1

This iterates through a variable number of columns of a particular row, which in this case is the 1st row:

$rownumber = 1;
$row = $this->objPHPExcel->getActiveSheet()->getRowIterator($rownumber)->current();

$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false);

foreach ($cellIterator as $cell) {
    $cell->getStyle()->getFont()->setBold(true);
}
