saving jpgs off the web using php

[scorpion]

How can you dynamically retrieve an image from an HTTP resource and save that image to your site using PHP?

Also is there a way to check if a file on your site exists? Anybody have a pointer to file i/o functions?
Thanks

well the logic of doing this would be
open it
read it
save it

As far as hecking to see if a file exists on your site. You can open a dir and check. I usually use the dir object and read through the filenames in it.

I see, so you can only "put" a file to an ftp resource? So my script is at say www.mysite.com/script.php, I want to write the file to mysite.com/afile.txt...

The script on your site can go out and grab anything it likes and then save it with in its own directory structure. It opens the file on some server, reads it into a var and then writes it to the machine it lives on.

You aren't trying to put it onto another server so it should work just fine.

thanks, I can see this working for text files, but would it also work to save a graphic file off the web onto your local server?

Yes it would, but be careful, you are getting into copyright issues by taking other peoples graphics!

Also, beware of how you handle the contents of the image. If you accidently have everything escaped, your image will just get broken. Just something to try to remember when playing around with it.
