Getting cells by coordinate - php

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();
}

Answer 2

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"

Answer 3

Rather than iterate all the Cells in a row, when not use the rangeToArray() method for the row, and then use array_intersect_key() method to filter only the columns that you want:
$worksheet = $objPHPExcel->getActiveSheet();
$highestColumn = $worksheet->getHighestColumn();
$columns = array_flip(array('A','C','E'));
foreach($worksheet->getRowIterator() as $row)
{
$range = 'A'.$row->getRowIndex().':'.$highestColumn.$row->getRowIndex();
$rowData = $worksheet->rangeToArray( $range,
NULL,
TRUE,
TRUE,
TRUE);
$rowData = array_intersect_key($rowData[$row->getRowIndex()],$columns);
// do what you want with the row data
}
EDIT
The latest SVN code introduces a number of new methods to th iterators, including the ability to work with ranges, or set the pointer to specific rows and columns
