View upload files on an HTML page

Navigation

I'm developing a Physics Study website, where the Teacher uploads files for student viewing. Except for the url in the database and the file in a folder. I am unable to view the pdf file on the page.

I'm using the iframe tag to view. I have seen many comments that this tag is not appropriate for such use. 

<iframe src='http://docs.google.com/gview?url=http://localhost/hammer/<?php $arquivo?>&embedded=true' style='width:600px; height:400px;' frameborder='0'></iframe>

I use the variable $ file to get the url in the database.

Can anyone help me?

If you echo this php <?php $arquivo?> and take into account what our friend Gustavo Castro said " will google can access your file since you are using via localhost? " . It will definitely work.

<?php echo $arquivo ?> 

<iframe src='http://docs.google.com/gview?url=<?php echo $arquivo?>&embedded=true' style='width:600px; height:400px;' frameborder='0'></iframe>

Use $ file=" http://infolab.stanford.edu/pub/papers/google.pdf ";

in the iframe edited above and see if it works

will google get access to your file since you are using via localhost? try to place your code in the cloud or elsewhere and check if your files are accessible.
I believe your file is inaccessible. 

<iframe src="http://docs.google.com/gview?url=http://infolab.stanford.edu/pub/papers/google.pdf&embedded=true"
 style="width:600px; height:500px;" frameborder="0">
</iframe>

Hello. 

<iframe src='http://docs.google.com/gview?url=http://localhost/hammer/<?php echo $arquivo?>&embedded=true' style='width:600px; height:400px;' frameborder='0'></iframe>

Even adding echo is not right, is it saving my cloud files right?
