This article describes the PHP implementation of the CSS file background image download code. Share to everyone for your reference. The implementation methods are as follows:
Download the CSS file inside the background picture is we these pirates for a long time to do things, download a CSS Picture downloader often appear all kinds of advertising bomb window, really can't carry. Here is a PHP version of the CSS file background image download to everyone.
Put the file into the PHP directory dos below php.exe cssimages.php 0 http://www.xxxx.com/css/style.css \images\
First in the PHP program directory to build a images folder, hehe, paste code:
Copy Code code as follows:
