但是，如第一个链接所示，这通常是使用Javascript完成的.您可以采用类似于第一个链接上显示的方法的方式输出Javascript，以强制浏览器显示打印对话框.

However, as the first link shows, this is usually done with Javascript. You can output Javascript in a way similar to the methods shown on the first link to force the browser to show the print dialog box.

您可以使用 file_get_contents 将文件打印到变量或输出流.

You can use file_get_contents to print files into a variable or to the output stream.

$filecontents = file_get_contents("myfilename.txt");
print $filecontents;
