Re: [PHP] save file from outside url
Ok. I stripped the needed code out of the image creation script and
inserted it into my update script. It works great as long as I hard
code in the filename of the file that is being saved to the server.
When I pass the image creation function a variable for the filename it
tells me "invalid filename", although I am echoing it out right before
and it looks perfect. Any thoughts?

Two things you need to do:
1) Plug the value of $rollover_image_url into a browser and satisfy yourself
that the resulting URL does indeed return a valid image, and hence said URL
is valid.
2) Plug in a known, static, valid URL (of an image -- actually it can be
anything it doesn't really matter) into your code below, and satisfy yourself
that the your code does work.

Re: [PHP] save file from outside url
Thanks for responing Jason!
There is other code in there for updating some database entries and
producing a confirmation page, but I had them working perfectly before I
added the image code below. Only when acessing the outside script and
saving to file did it start doing the odd things. I didn't write the image
creation script, only hard coded in some values for font and bg colors in
it. I have attached that script at the bottom of this, away from everything
else. Maybe a header problem from that script? Any idea what 427 is from?
Thanks for all your help!
The $image_url is like this - "$rollover_image_url =
"http://www.anysite.com//pngmake.php?msg="; . $rollover .
"&rot=0&size=12&font=fonts/ARIAL.TTF";

Hmm, I don't see how the above code can make the remote image *display* your
browser. The code itself looks OK, are there some parts of the code that you
haven't shown us?
If the above is indeed your complete code, then what is your $image_url?
