从单个网页下载所有图像

Question

I'm experimenting with PHP, and I've just asked myself a question. How can I download all images from a single website? Let's say that I wanted and images from cnn.com or any other website. Is there any easy way I can download all the images using PHP, and save them on my local computer (or FTP server).

Any help would be appreciated.

Answer 1

If you wanted just all download all images referenced by img elements.

1. Request the remote file with something like cURL.
2. Use a DOM parser (such as DOMDocument) to get all img element.
3. Iterate over the img elements and use cURL (or similar) to download each image (check the src attribute).
