What I do:
How can I found \n and insert new line? For example I have in A1 next text "One\nTwo". I read text from A1
$ltr='A1';
$vle=$spreadsheet->getActiveSheet()->getCell($ltr);
After this I try to insert text in A1 again in A1 and replace \n with new line in one cell
$spreadsheet->getActiveSheet()->getCell($ltr)->setValue("${vle}");
$spreadsheet->getActiveSheet()->getStyle($ltr)->getAlignment()->setWrapText(true);
But it does not work for my.
So, if I open tamplate with text I can't replace \n in cells. What can I do?
Upd. I try use char(10) and insert formula (for example) ="hello"&char(10)&"world"
But inserted only ="hello"&char(10)
When I explode/implode str and insert \n I use ''. Need use ""
implode("\n", $array);
