PHPExcel fast duplicate row - php

Question

I have row with different styles for each cell. I need to duplicate it (copy text, style, size).
I was using following function to do it:
function copyRowFull(&$ws_from, &$ws_to, $row_from, $row_to) {
$ws_to->getRowDimension($row_to)->setRowHeight($ws_from->getRowDimension($row_from)->getRowHeight());
$lastColumn = $ws_from->getHighestColumn();
$rangeFrom = 'A'.$row_from.':'.$lastColumn.$row_from;
// copy text
$ws_to->fromArray($ws_from->rangeToArray($rangeFrom), null, 'A'.$row_to);
// copy style
++$lastColumn;
for ($c = 'A'; $c != $lastColumn; ++$c) {
$ws_to->duplicateStyle($ws_from->getStyle($c.$row_from), $c.$row_to);
}
}
However it it VERY slow due to loop but I need it fast because many rows will be copied.
Also I have tried this for style copying:
$rangeTo = 'A'.$row_to.':'.$lastColumn.$row_to;
$ws_to->getStyle($rangeTo)->applyFromArray($ws_from->getStyle($rangeFrom));
But it doesn't work - throws error "Invalid style array passed".
Is there any faster method?

After crawling in PHPExcel sources, I have figured out a lot faster way to duplicate row. It works copying only inside one workbook but it is what I needed. Posting it, maybe someone also had or will have similar problem.
function copyRowFull(&$ws_from, &$ws_to, $row_from, $row_to) {
$ws_to->getRowDimension($row_to)->setRowHeight($ws_from->getRowDimension($row_from)->getRowHeight());
$lastColumn = $ws_from->getHighestColumn();
++$lastColumn;
for ($c = 'A'; $c != $lastColumn; ++$c) {
$cell_from = $ws_from->getCell($c.$row_from);
$cell_to = $ws_to->getCell($c.$row_to);
$cell_to->setXfIndex($cell_from->getXfIndex()); // black magic here
$cell_to->setValue($cell_from->getValue());
}
}

For those on PHP 5.3 or so, Somnium's answer blended with Ravean's comment and adapted for PHP 5.3:
/**
* Copies entire row with formatting and merging
* #param $ws_from
* #param $ws_to
* #param $row_from
* #param $row_to
* #throws PHPExcel_Exception
*/
public function copyRowFull(&$ws_from, &$ws_to, $row_from, $row_to)
{
$ws_to->getRowDimension($row_to)->setRowHeight($ws_from->getRowDimension($row_from)->getRowHeight());
$lastColumn = $ws_from->getHighestColumn();
++$lastColumn;
for ($c = 'A'; $c != $lastColumn; ++$c) {
$cell_from = $ws_from->getCell($c . $row_from);
if ($cell_from->isMergeRangeValueCell()) {
$pCoordinateString = PHPExcel_Cell::splitRange($cell_from->getMergeRange());
$coordinateFromString = PHPExcel_Cell::coordinateFromString($pCoordinateString[0][1]);
$col = $coordinateFromString[0];
$ws_to->mergeCells($c . $row_to . ':' . $col . $row_to);
//$cell->getMergeRange()
}
$cell_to = $ws_to->getCell($c . $row_to);
$cell_to->setXfIndex($cell_from->getXfIndex()); // black magic here
$cell_to->setValue($cell_from->getValue());
}
}
