我有一个问题要问你，所以我尝试使用dompdf导出带有php的pdf文档，一切都很顺利，但当我发送php变量来显示时，它会添加到末尾和开头。%27
public function generateTitlePage($number_cadastral='')
{
$this->load->library('dompdf_gen');
$dompdf = new DOMPDF();
$html = <<<HTML
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" type="text/css" media="screen" href="TitlePage.css" />
</head>
<body>
<div style="margin-top: 100px; text-align: right; padding-right:100px;">
Number:$number_cadastral
<div style="width: 150px;margin-left: 535px;size:1;"><hr style="margin:0px;"></div>
</div>
<div>
</body>
</html>
HTML;
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("welcome.pdf");
在这种情况下，变量$number_cadastral在前面。%27，那么结果将是：%27.7787883434.%27为什么要加这个%27？？请帮帮我
<?php
$number_cadastral = ($number_cadastral != "")?preg_replace('/[%]+/','', $number_cadastral):"";
public function generateTitlePage($number_cadastral){
$this->load->library('dompdf_gen');
$dompdf = new DOMPDF();
$html = '
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" type="text/css" media="screen" href="TitlePage.css" />
</head>
<body>
<div style="margin-top: 100px; text-align: right; padding-right:100px;">
Number:'.$number_cadastral.'
<div style="width: 150px;margin-left: 535px;size:1;"><hr style="margin:0px;"></div>
</div>
<div>
</body>
</html>
';
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("welcome.pdf");
}
?>
试试这个代码。
