The example in this article describes the CSS file background image downloader code implemented in PHP. Share it with everyone for your reference. The specific implementation method is as follows:

Downloading background images in css files is something we pirates have been doing for a long time. When downloading a css image downloader, various advertising pop-ups often appear, which is really unbearable. Here we provide a php version of css file background image downloader for everyone.

Put the file under dos in the php program directory php.exe cssImages.php 0 http://www.xxxx.com/css/style.css images

First create an images folder in the php program directory, haha, paste the code:

Copy code The code is as follows:

/**

set_time_limit(0);
error_reporting(E_ERROR);
if($argc<4){
print_r('
