我已经尝试了以下在 DOMPDF 的常见问题页面中提到的内容。并没有成功。注意：我还打开了内联 PHP 以及常见问题解答中提到的
following is my code
以下是我的代码
<?php
require_once("dompdf/dompdf_config.inc.php");
ob_start();
//be sure this file exists, and works outside of web context etc.)
$dompdf = new DOMPDF();
$html=" <script type='text/php'>";
if ( isset($pdf) ) {
$font = Font_Metrics::get_font("yourfont", "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);
}
$html.=" </script>";
$html .="
aaaaa<br/>aaaaaa<br/>aaaaaa<br/>aaaaa<br/>aaaaaa<br/>aaaaaa<br/>aaaa<br/>aaaaa<br/>aaaaaa<br/>aaaaa<br/>
aaaaa<br/>aaaaaaa<br/>aaaaaa<br/>
aaaaa<br/>aaaaaa<br/>
aaaaaaa<br/>aaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
aaaaaaa<br/>aaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>

aaaaaaaa<br/>aaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
aaaaaaaaa<br/>aaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>aaaaaaaaaaaaaaaaa<br/>
</body></html>";
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");
?>
Can someone point me out this issue please? where did i make it wrong
有人可以指出我这个问题吗？我哪里做错了

You are running your inline script as part of the PHP page instead of passing it to dompdf. Your code couldbe written as follows (truncated to the relevant section):
您将内联脚本作为 PHP 页面的一部分运行，而不是将其传递给 dompdf。您的代码可以写成如下（截断到相关部分）：
...
$html="
<html>
<body>
<script type='text/php'>
if ( isset($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>
";
...
Note that inline script must currently appear inside the BODY element. Otherwise it will be ignored during document processing.
请注意，内联脚本当前必须出现在 BODY 元素内。否则在文档处理过程中将被忽略。

Where you have '1/1' being used to get $x, this won't work when you have more than 10 pages.
如果您使用“1/1”来获取 $x，当您有 10 个以上的页面时，这将不起作用。
A possible solution does mean editing "cpdf_adapter.cls.php", so the _add_page_text() function used the following just after the str_replace()... about line 790:
一个可能的解决方案确实意味着编辑“cpdf_adapter.cls.php”，因此 _add_page_text() 函数在 str_replace() 之后使用了以下内容...大约第 790 行：
if ($x < 0) $x = (($this->_width + $x) - $this->get_text_width($text, $font, $size));
if ($y < 0) $y = (($this->_height + $y) - $this->get_font_height($font, $size));
The idea is that you can pass in negative x/y coords, and they will work from the right/bottom edges.
这个想法是你可以传递负 x/y 坐标，它们将从右/下边缘开始工作。
Then in the HTML thats sent to DOMPDF, I used:
然后在发送到 DOMPDF 的 HTML 中，我使用了：
<script type="text/php">
$pdf->page_text(-30, -32, "{PAGE_NUM} of {PAGE_COUNT}", Font_Metrics::get_font("serif"), 10, array(0,0,0));
</script>
Or if you want to specify the x/y in px:
或者，如果您想以 px 为单位指定 x/y：
<script type="text/php">
$pdf->page_text(((-30 * 72) / DOMPDF_DPI), ((-32 * 72) / DOMPDF_DPI), "{PAGE_NUM} of {PAGE_COUNT}", Font_Metrics::get_font("serif"), 10, array(0,0,0));
</script>
