using curl to read timestamp of and SAVE network file

[sfullman]

Hi,

I've used curl before but this is a new thing for me to pull files off a network and save them, ESPECIALLY binary files like images.

How would I:
1. read the timestamp of a file on the web (from experience, a browser can do this because it will refresh a .js file if it has changed )

2. save a file, esp. a binary file that is on the web, to my server.

I am assuming that curl is the way to go on this, please tell me if PHP has a better way.

Thanks,
Samuel

Just to clarify, is the file on a remote server only accessible to your script via HTTP (and thus the need to use cURL), or is it on the same server or available via a LAN where you could access it via file system functions?

If the former (cURL), take a look at the [man]curl_getinfo/man function. If the latter, take a look at [man]filemtime/man.
