How can I save an image by PHP?

Question

I have a script which generates an image. I have used it like this so far:

<img src='/img/avatar/identicon.php?size=35&hash=64d134jf23tgr7k' height='40' width='40'>

Now I'm trying to store it as a image in this path:

/img/avatar/$id.jpg

And then use it like this:

<img src='/img/avatar/$id.jpg' height='40' width='40'>

How can I store that image as a real image in a folder?

Note: I have id as a dynamic variable, and I want to use it as the name of image.

You'll need to save the image first, here's one way to do it:

$id = "someID.jpg";
file_put_contents("img/avatar/".$id, file_get_contents("http://somesite/img/avatar/identicon.php?size=35&hash=64d134jf23tgr7k"));

then use it like this:

<img src='/img/avatar/<?=$id?>' height='40' width='40'>
