@Mark Baker Thank you for show the way I tried and done like this -

$calculatRow='';
    for($ctr=0;$ctr < count($marksColumnArr);$ctr++)
    {
    $calculatRow.='(($'.$marksColumnArr[$ctr].'##/$'.$maXmarksColumnArr[$ctr].'$##)*'.$divisionVal[$ctr].')+';      
}
$calculateArrbyRow=substr($calculatRow,0,-1);    
// Replicate formula by row

 for($j=5;$jgetActiveSheet()->setCellValue($cell.$j, '='.$formula);
 }    
$coumnStart=($coumnStart-1)+13; $subjectCtr++;
}
