Is php capable of doing what I want?

Question

I'm working on a biology web based application and trying to figure out what language to use. The features I need to include are:

• Image viewing frame - This area will display the current image that the biologists wish to see. The application needs to take in a number of coordinates from a file and draw those points on the image displayed here. When the biologist wishes to change images there needs to be no flickering from the refresh. Will do this using multiple image buffers probably. Content needs to be scrollable and able to be zoomed in.
• There need to be labeled buttons that advance, step back, zoom, and play the images displaying in the image frame. There also needs to be some type of list view where images titles can be selected to be displayed.
• There will be a bunch of folders of images on the server that can be selected from. The application must allow the user to select which folder of images to be loaded. It also must be able to read from either an txt or xml file and visually display the information there by way of line graph.
• Would like to be able to run scripts on the server from the application.

I feel that all these things are doable by a web application but I have no idea what language to use. Most people recommend php, but i don't want to delve deeper until I know what its limitations are. Any suggestions are welcome. Thanks in advance.

PHP can do everything you need for the back end, but most of the stuff that you describe is UI based, and this is dependent on the client, which is, of course, the browser. For highly graphical projects, you can do a lot in JavaScript and some JavaScript libraries have a lot of these capabilities built in. You might also consider Flash or Flex.

You might even consider a desktop application that runs outside of the browser. You can use Java, which is easy to deploy, but still requires the user to have the Java Runtime Engine, or you could go with a language that you can compile down to a native application.

Regardless of the front end technology that you choose, you'll still need a back end, and PHP can handle this.
