Generate filename with creation date
提问by denully
I'm using dompdf to create and mail a PDF file to my mail and at the same time, save a .txt version on the server. Saving the file is working as it should, but im having a bit of trouble getting it to save it with a unique name. In this case i wanted something like date-time.txt ( 06-09-2012_11:43.txt )
我正在使用 dompdf 创建一个 PDF 文件并将其邮寄到我的邮件中，同时在服务器上保存一个 .txt 版本。保存文件正常工作，但我在使用唯一名称保存文件时遇到了一些麻烦。在这种情况下，我想要类似 date-time.txt ( 06-09-2012_11:43.txt )
or even better, if it could have the name from the text field "refnr" as the name.
或者甚至更好，如果它可以将文本字段“refnr”中的名称作为名称。
<label for="refnr"><b>Referensnummer:</b></label>
<input type="text" name="refnr" id="refnr" class="input" />
The code looks like this:
代码如下所示：
$html = '/html.php';
$filename = $dir.'/Admin/files/"date here".txt';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper('a4', 'portrait');
$dompdf->render();
file_put_contents($filename, $dompdf->output());
I tried to play around with $name='myfile_'.date('m-d-Y_hia)';but couldn't make that work, it just gave an error on that line every time.
So now im here to seek the guidance from you smart people :)
我试图玩，$name='myfile_'.date('m-d-Y_hia)';但不能让它工作，它每次都在那条线上出错。所以现在我在这里寻求聪明人的指导:)

You put the )before you closed the string format code:
您)在关闭字符串格式代码之前放置了：
$name='myfile_'.date('m-d-Y_hia');
Should work fine.
应该工作正常。
As Jan1337z points out, you probably wanta suffix on the file:
正如 Jan1337z 指出的那样，您可能需要在文件上添加后缀：
$name='myfile_'.date('m-d-Y_hia').'.txt';
Not having a suffix should't stop the file being created - but having it will probably help make it easily usable.
没有后缀不应停止正在创建的文件 - 但拥有它可能有助于使其易于使用。
