I've the above line of code. The problem is, I am not good at iterating and I want all the cell values to be set as STRING so as to avoid automated modifications of texts leading zeros.

P.S. In Addition, code for setting as STRING for selective columns will be appreciated.




When you set cell values individually, you have the option of setting the datatype explicitly, but when you use the fromArray() method, you don't have this option.

However, by default, PHP uses a default value binder to identify datatypes from the values passed, and set the cell datatype accordingly. This default behaviour is defined in a class /PHPExcel/Cell/DefaultValueBinder.php.

So you can create your own value binder, as described in the PHPExcel Documentation, that would set every value as a string datatype.

Something like:

class PHPExcel_Cell_MyColumnValueBinder extends PHPExcel_Cell_DefaultValueBinder implements PHPExcel_Cell_IValueBinder
    protected $stringColumns = [];

    public function __construct(array $stringColumnList = []) {
        // Accept a list of columns that will always be set as strings
        $this->stringColumns = $stringColumnList;

    public function bindValue(PHPExcel_Cell $cell, $value = null)
        // If the cell is one of our columns to set as a string...
        if (in_array($cell->getColumn(), $this->stringColumns)) {
            // ... then we cast it to a string and explicitly set it as a string
            $cell->setValueExplicit((string) $value, PHPExcel_Cell_DataType::TYPE_STRING);
            return true;
        // Otherwise, use the default behaviour
        return parent::bindValue($cell, $value);

// Instantiate our custom binder, with a list of columns, and tell PHPExcel to use it
PHPExcel_Cell::setValueBinder(new PHPExcel_Cell_MyColumnValueBinder(['A', 'B', 'C', 'E', 'F']));

$objPHPExcel = new PHPExcel();

You need to iterate over your results, adding a new entry to the output when you encounter a new team, or updating the points value when you find the same team again. This is most easily done by initially indexing the output by the team name, and then using array_values to re-index the array numerically:

$teams = array();
foreach ($results as $result) {
    $team = $result['team'];
    if (!isset($teams[$team])) {
        $teams[$team] = array('team' => $team, 'points' => $result['punti']);
    else {
        $teams[$team]['points'] += $result['punti'];
$teams = array_values($teams);

Output (for your sample data):

    [0] => Array
            [team] => Red Bull Racing
            [points] => 418
    [1] => Array
            [team] => Scuderia Ferrari
            [points] => 353
    [2] => Array
            [team] => Mercedes-AMG
            [points] => 516
    [3] => Array
            [team] => Racing Point F1
            [points] => 147
    [4] => Array
            [team] => Haas F1
            [points] => 127

There is currently no method in PHPExcel that will allow you to set the data type for a range of cells, only for an individual cell.

There are a couple of options... the harder would be to write a custom Cell Value Binder that automatically sets the data type for those cells to string when the cell value is set by fromArray().

What you could do instead (and is far easier), is to leave the datatype as a number, and the value as a numeric, but to set a number format mask which tells Excel to display the numbers with leading zeroes.

$keyCell = $sheet->getCellByColumnAndRow(1,5)->getValue();

Will read the cell data in the format that it's actually stored by Excel, you can't arbitrarily change that or tell PHPExcel to read it as a different datatype.

However, if the cell has formatting applied, then you can use

$keyCell = $sheet->getCellByColumnAndRow(1,5)->getFormattedValue();

instead, and this will return the data as a string, with whatever format mask was defined in the Excel spreadsheet

You can do it like this, do the calculation from the innermost of the array. Check the demo.

function f(&$array)
    foreach($array as $k => &$v)
            if(count($v) == count($v, 1))
                if($k == 'sum')
                    $v =  array_sum($v);
                    $array[] = $v;

                }elseif($k == 'multiply'){
                    $v = array_product($v);
                    $array[] = $v;

                    foreach($v as $vv)
                        $array[] = $vv;

while(count($array) != count($array, 1))
