Is it possible, using PHP, to display an individual pages from a pdf file. For example if I have a 5 page pdf file and I wish to display only the n-th page?
I did some google searching on this but nothing useful came up really, so I wonder if it's possible at all.
Thank,

I'm very new to PHP and wanted to know how to create a single download link for 2 pdf files using php. Do I need to write an individual download.php file to execute or can I simply add it to my index page using an tag in html? I need it to work across all browsers.
I have 2 documents that are in their own folder named "forms" and not sure how to create a simple text link that will let a user download both documents in a single click.
I agree with the other answers, this is not the best practice, you should use one button/link for each file, it's even easier to understand what's been displayed for the user. You should probably use two icons or links.
Look up for w3schools, they have good tutorials of how to use icons, links, html, css and javascript.
There are some links:

I need to display all students detail in the table format while clicking the "Print" link in my web page. Users may print these records in this page. It may have several thousands of records.
Because of this, it took more time to load. Is it possible to load records page by page? Or am i need to do any other thing to reduce the loading time?
Please advice.
Note: I have optimized my code as much as possible as per the Google search.
I would install wkhtmltopdf, I would use a html template, then generate a pdf file using the html template when changes are made to the list, and download that file when needed.
This way, you save processing power, and the users download the same file.
Also, by doing so, most browsers know how to render a pdf file without downloading it
Yes, using CPagination class
You have an example in that Doc page.
You will have to paginate the records, if they are in DB, Yii will instruct the db engine to only retrieve the records in a range, making it efficiently.
How could I use imagegrabscreen to get a thumbnail image and a full size image of a specific website.
I was thinking that I could have an array that I feed the wanted uri's into but I am a bit stuck on how I would set the wxh of the image I need to grab. I also think that I would need a thumbnail class and a fullimage class and call them when required.
Any better Ideas?
Keep in mind that imagaegrabscreen is Windows-only. If you have multiple displays set up, this function will only grab the primary display. Also, for this to work, your Apache service must be set to Allow service to interact with desktop otherwise you will just get a blank image.
This discussion covers the use of imagegrabscreen pretty well: Getting imagegrabscreen to work
There are a lot of other discussions about saving webpages as images, too - here are a few:

I am currently adding images to the page new on this website but some images I would like to add to the various catagory pages such as new in, crop circles or childrens without having to upload to the different pages seperatley one at a time.
Is there a way to dynamically add the images to other relevant pages depending on the class of the image without having to upload to each page individually using php or ajax which would save lots of time.
or is there a plugin where I can add images to multiple pages at once?
I figure this is an ajax issue but am hoping there is a php wordpress solution.
It would be fab if anyone can help.
umm.. Actually, I dont know any wordpress solution, If I were you, I would create a simple php which can do that logic for you and render a JSON file with your images struct?!
hey guys so im building an application and one of teh features it will have is the ability to show photo links from twitter inline sort of like what tweetdeck has done in their chrome browser version and sites like crowdreel have been able to do, i spent some time researching how to grab image tags from urls on google and found this fantastic script http://www.bitrepository.com/extract-images-from-an-url.html
the script is great and does exactly what i need, however now my challenge is that the array returned from the links returns every image in the page including thumbnails ads etc, so a link to a page like this: http://lockerz.com/s/69901787
will return an array with quite a few image links to sort through,
however what i need is a link to the main image so that i can display it inline with tweets, my idea is that i run some sort of code to figure out which of the images in the page is the largest? what are your thoughts on this? is this the right method or is there something easier thats built into php perhaps? thanks for all your help guys!
Once you have the links to the images you can pass them to the getimagesize() function in PHP.
Look at this example: http://php.net/manual/en/function.getimagesize.php#example-2267
