After setting lineHeight, how to make the text vertically centered?

You'll need to set the same spacing before and after (spaceBefore and spaceAfter)

[HuPengCheng1994]

set number has no effect
$section->addText("PHPWord is a library written in pure PHP that provides a set of classes to write to and read from different document file formats",['size'=>18],['spaceBefore ' => 200,'spaceAfter'=>200]);

you put a space after spaceBefore ...

$section->addText('Vertically centered text', array('size'=>18), array('lineHeigth' => 600,'spaceBefore' => 200,'spaceAfter'=>200));
