Getting cells by coordinate

Question

foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {

    foreach ($worksheet->getRowIterator() as $row) {
        $cellIterator = $row->getCellIterator();
        $cellIterator->setIterateOnlyExistingCells(false);
            // I wish
            echo $cellIterator->getCell("A3"); // row: $row, cell: A3
    }
}

I'm looking for a similar method which named getCell above or well-writed PHPExcel documentation.

Thanks.

Answer 1

If you have the $row information from RowIterator, you can just easily call:

$rowIndex = $row->getRowIndex ();
$cell = $sheet->getCell('A' . $rowIndex);
echo $cell->getCalculatedValue();

The complete code would be:

foreach($worksheet->getRowIterator() as $row){
    $rowIndex = $row->getRowIndex();

    $cell = $worksheet->getCell('A' . $rowIndex);
    echo $cell->getCalculatedValue();
    $cell = $worksheet->getCell('B' . $rowIndex);
    echo $cell->getCalculatedValue();
}

This is what I needed:

function coordinates($x,$y){
 return PHPExcel_Cell::stringFromColumnIndex($x).$y;
}

implementation:

coordinates(5,7); //returns "E7"

Though one could also do this for A-Z columns:

function toNumber($dest)
{
    if ($dest)
        return ord(strtolower($dest)) - 96;
    else
        return 0;
}

function lCoordinates($x,$y){
 $x = $toNumber($x);
 return PHPExcel_Cell::stringFromColumnIndex($x).$y;
}

implementation:

lCoordinates('E',7); //returns "E7"
