A pdf document contains two pages. In each page of the pdf file there may be text,image or any graphics object.
But it may be possible sometimes that in the second page there may be no content, though the page may be present.

Now it is required for me to know whether the second page is blank or not.

Can any body suggest me how can I achieve this. I need to do it in PHP.  If anybody can provide some sample code and  can suggest some library it will be very much helpful.

Thanks in advance.
