$sheet->setCellValue('A1', "Hello World !\nHello World !!\nHello World !!!");
$sheet->getStyle('A1')->getAlignment()->setWrapText(true);

// Using single quotes will not make the line break work
// Set cell B1 value with the three "Hello World !", one on it's own line
$sheet->setCellValue('B1', 'Hello World !\nHello World !!\nHello World !!!');
$sheet->getStyle('B1')->getAlignment()->setWrapText(true);

// Using single quotes and appending the line break with double quotes
// Set cell C1 value with the three "Hello World !", one on it's own line
$sheet->setCellValue('C1', 'Hello World !' . "\n" . 'Hello World !!' . "\n" . 'Hello World !!!');
$sheet->getStyle('C1')->getAlignment()->setWrapText(true);
