Hi, how can I display 2 different fonts in the same text separated by a new line?

$font1 = "font1.ttf";
$font2 = "font2.ttf";
$text1 = "text";
$text2 = "text2";

$box = new Box($im);
$box->setFontFace($font1);
$box->setFontColor(new Color(255, 255, 255));
$box->setTextShadow(new Color(0, 0, 0, 50), 2, 2);
$box->setFontSize(35);
$box->setBox(100, 150, 500, 400);
$box->setTextAlign('center', 'center');
$box->draw($text1."\n".$text2); // here only displays the second text with the font1
