以下是我的代码
<?php

$html=" <script type='text/php'>";

$dompdf->render();
$dompdf->stream("sample.pdf");
?>
有人可以指出这个问题吗?我在哪里弄错了
Can someone point me out this issue please? where did i make it wrong
推荐答案
您正在将内联脚本作为PHP页面的一部分运行，而不是将其传递给dompdf.您的代码可以编写如下(截短至相关部分):
You are running your inline script as part of the PHP page instead of passing it to dompdf. Your code could be written as follows (truncated to the relevant section):
...
$html="
<html>
<body>
<script type='text/php'>
if ( isset($pdf) ) {
$font = Font_Metrics::get_font('helvetica', 'normal');
$size = 9;
$y = $pdf->get_height() - 24;
$x = $pdf->get_width() - 15 - Font_Metrics::get_text_width('1/1', $font, $size);
$pdf->page_text($x, $y, '{PAGE_NUM}/{PAGE_COUNT}', $font, $size);
}
</script>
";
...
请注意，内联脚本当前必须出现在BODY元素内.否则它将在文档处理过程中被忽略.
