I use this code before closing the foreach tag: $html .= "<pagebreak />";
我在关闭 foreach 标记之前使用此代码： $html .= "<pagebreak />";
foreach($matches as $value) {
$html .= "<pagebreak />";
}

I've been successful without using AddPage and instead using css to add the page break, with page-break-after:alwaysand for the last div, page-break-after:avoid. Maybe something like this would work:
我没有使用 AddPage 而是使用 css 添加分页符，page-break-after:always以及最后一个 div，page-break-after:avoid. 也许这样的事情会起作用：
$len = count($matches);
$i = 1;
foreach($matches as $value) {
if ($i < $len) {
$html .= "<div style='page-break-after:always'>" . $html . "</div>";
} else {
$html .= "<div style='page-break-after:avoid'>" . $html . "</div>";
}
$i++;
}
$mpdf->WriteHTML($html);
