Finding files incrementally

[Nick99]

Hey, I would know how to find files incrementally in PHP. I'm having a hard time finding examples. By incrementally i mean like, find one file, then go on to another. Any help is appreciated.

Can you describe your situation more? What's different from just finding 2 files? EDIT: And what do you mean by "finding" files - opening them?

[Nick99]

I mean like, find a file, display it, find another file, display it, find another, and so forth

So you have a list of files and the user should see each in turn. Write a page that shows one file, whose name (or index in an array of filenames) was passed via GET. To that page, add either a Next (and Previous) button or a menu with all files listed. Make the button(s)/menu change the GET parameter when clicked.

No, I mean find any file in the directory, and display it

you can use glob() to get all files in a directory, and fopen and fread to get the contents of the file

Be careful with that, though; you don't want the user to see just any file on your server. You should implement some kind of filter for the user input so, for example, they can't use "../filename" to go up the directory tree. If you do that and only put files that aren't "classified" into that directory, I think that should be enough.
