Mpdf php mysql选择限制记录

Question

从数据库中选择记录：

$dados = mysql_query($query_dados, $valesilveira) or die(mysql_error());
# $totalRows_dados = mysql_num_rows($dados); # you don't need this unless you're using
                                   # $totalRows_dados somewhere else

# check for number of results. If there are none, exit / die / return / whatever
if (mysql_num_rows($dados) == 0) {
echo "no results found!";
# die / exit / return false / etc.
}

# initialise a string to hold the articles
$articles = '';

# loop through the results one at a time
while ($row_dados = mysql_fetch_assoc($dados)) {
# append the article div on to our existing string
$articles .= '

<div id="articles">
<div class="titulobold"><p>&nbsp;'.$row_dados['titulo'].'</p></div>
<div class="wid10"><p>'.$row_dados['posicao'].'</p></div>
<div class="wid15"><p><img src="images/artigos/'.$row_dados['folder'].'/'.$row_dados['id_artigo'].'.png" style="height:60px;" /></p></div>
<div class="wid30"><p>&nbsp;'.$row_dados['desc'].'</p></div>
<div class="wid15"><p>'. number_format( $row_dados['unitario'], 2 ) .'€</p></div>
<div class="wid15"><p>'. number_format( $row_dados['unitario']*$row_dados['quantidade'], 2 ) .'€</p></div>
<div class="wid10"><p>'.$row_dados['quantidade'].'</p></div>
</div>

';

// any other stuff you want to do to each piece of row data can go here

}

但由于某些原因，我的工作并不像我想要的那样，因为在每一页中，记录都会开始上升，但是有了更多信息的图像会出现错误：

它继续像一个循环一样上升。

请告诉我该怎么做。

$mpdf->SetHTMLFooter($footer);

// LOAD a stylesheet
$stylesheet = file_get_contents('css/print.css');
$mpdf->WriteHTML($stylesheet,1);    // The parameter 1 tells that this is css/style only and no body/html/text

$mpdf->WriteHTML($articles);

$mpdf->Output();

exit;
