++++return+count($this->pages);
}|code-block|syntax|javascript|373380|然后添加html解析器，如下所示：|373381|$html+=+str_replace('{PAGECNT}',+$this->getPageCount(),+$html);|373382|完成这些操作后，您可以在解析后的HTML中直接插入{PAGECNT}以获得结果。这是很有用的，因为你需要指明一个页面：|373383|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

add this to a main mPDF class:

<pre><code>function getPageCount() {
 return count($this-&gt;pages);
}
</code></pre>

then add a html-parser such string:

<pre><code>$html = str_replace('{PAGECNT}', $this-&gt;getPageCount(), $html);
</code></pre>

after these actions you can insert {PAGECNT} directly in your parsed HTML to get the result. This is useful is you need to indicate a page:

blocks|key|373415|text|我在使用EYiiPdf+(Yii上mPDF的一个包装器)时也在寻找同样的功能，下面的代码效果很好：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|373416|$mPDF->setFooter('{PAGENO}+/+{nb}');|code-block|syntax|javascript|373417|我查看了mPDF的源代码，在mpdf.php:1656+(版本5.4)上找到了这个：|373418|function+AliasNbPages($alias='{nb}')+{

I was looking for the same functionallity while using EYiiPdf (a wrapper for mPDF on Yii) and the following worked like a charm:

<pre><code>$mPDF-&gt;setFooter('{PAGENO} / {nb}');
</code></pre>

I checked mPDF's source and found this at mpdf.php:1656 (version 5.4):

<pre><code>function AliasNbPages($alias='{nb}') {
 //Define an alias for total number of pages
 $this-&gt;aliasNbPg=$alias;
}
</code></pre>

Hope it helps!

blocks|key|589178|text|如果您试图返回页数，以便将其保存到数据库或mpdf之外的其他操作中，则可以很容易地使用这种方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|589179|在你写完内容之后：|589180|$mpdf->WriteHTML($html);

If you are trying to return the number of pages so you can save this to a database or some other operation outside of mpdf it's easy to pull it this way.

After you write your content:

<pre><code>$mpdf-&gt;WriteHTML($html);
$page_count = $mpdf -&gt; page;

$mpdf-&gt;Output();
</code></pre>

blocks|key|373523|text|注意这条线：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|373524|preg_replace('/\{DATE\s%2B(.*?)\}/e',"date('\\1')",$hd);|offset|length|style|CODE|373525|在mpdf.php函数Footer()中，它可能导致您的"{PAGENO}+/+{nb}“不显示。只需将其注释掉或使用strpos('{DATE'+>+-1)检查它是否可用。另外，您可能需要添加以下内容：|373526|$mpdf->ignore_invalid_utf8+=+true;|373527|另外，如果你不想要脚注行：|373528|$mpdf->defaultfooterline+=+false;|code-block|syntax|javascript|373529|在这些更改之后，分页终于对我起作用了。|373530|entityMap^0|0|0|1I|0|1N|K|0|0|Y|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@$D|Y|E|Z|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|10|8|@$D|11|E|12|F|G]]|9|@]|A|$]]|$1|J|3|K|5|6|7|13|8|@$D|14|E|15|F|G]]|9|@]|A|$]]|$1|L|3|M|5|6|7|16|8|@]|9|@]|A|$]]|$1|N|3|O|5|P|7|17|8|@]|9|@]|A|$Q|R]]|$1|S|3|T|5|6|7|18|8|@]|9|@]|A|$]]|$1|U|3|-4|5|6|7|19|8|@]|9|@]|A|$]]]|V|$]]

Watch for the line: 

<code>preg_replace('/\{DATE\s+(.*?)\}/e',"date('\\1')",$hd);</code>

in mpdf.php function Footer()
It may cause your "{PAGENO} / {nb}" to not be displayed.
Just comment it out or use <code>strpos('{DATE' &gt; -1)</code> to check if it is available.
Also you may need to add: 

<code>$mpdf-&gt;ignore_invalid_utf8 = true;</code> 

and also if you don't want footer line:

<pre><code>$mpdf-&gt;defaultfooterline = false;
</code></pre>

After these changes the pagination worked for me at last.

Does anybody knows how to get the number of generated pages if a PDF document using mPDF library?
