I am developing a web application which needs the following functionality
1) Generation of graphs
2) Generation of calender format schedules for users
3) Automatic emails to users
4) uploading/downloading of video clips, images
5) Multiple list on one page, one list item brings another whole list, and one item from second list brings third list.

I would like to know how easy or convineint it would be to use PHP for this.

Please,any help is highly appreciated
Thank you.

1) PHP can generate images. Read the docs at php.net for more info.
2) It takes some advanced coding to do this depending on exactly what you want to do. You would have to use a database to hold data about these things. I believe you can find pre-made calendar PHP scripts online, just try googling for them.
3) Easily, but if you want to periodically do this without accessing the files, you would need cron jobs or scheduled tasks or something similar.
4) Yes, Rich has an excellent FAQ on this in the PHP FAQ forum.
5) Are you talking about a fold-up type list that shows and hides sub-lists? There are pre-made scripts that do this, but a better alternative would probably be JavaScript since you don't have to post back to the server. Check out javascript.internet.com for some examples.

Let me know if you need further explanations.

The two rules: 1) I am always wrong. 2) If I'm right, refer to rule number 1.

thnx snib,

well for the fifth point, i would like to knw if javascript is a stable choice to make since it is browser dependent and i donno how it works on different OS platforms too

thnx,

This is actually one thing that you can do on almost any browser (as long as JavaScript is enabled). If JavaScript is not enabled, you can display a message asking the user to enable it and refresh the page.

Like I said, check out http://javascript.internet.com or http://dynamicdrive.com for code examples.

HTH!
