I am looking for a simple way to import/copy images from remote server to a local folder using PHP. I have no FTP access to the server, but all remote images can be accessed via HTTP (i.e. http://www.mydomain.com/myimage.jpg).
Example use: A user wishes to add an image to his profile. The image already exists on the web and the user provides with a direct URL. I do not wish to hotlink the image but to import and serve from my domain.
If you have PHP5 and the HTTP stream wrapper enabled on your server, it's incredibly simple to copy it to a local file:
copy('http://somedomain.com/file.jpeg', '/tmp/file.jpeg');
This will take care of any pipelining etc. that's needed. If you need to provide some HTTP parameters there is a third 'stream context' parameter you can provide.
