PHP grabs and downloads all image files in css

if (!is_dir('img')) { mkdir('img'); }

> 3. Use regular expressions to get the relative address of the image:

if (preg_match('/^http.*/',$val)) { $target = $val; }
else if (preg_match('/^/.*/',$val)) { $target=$host.$val; }
else { $target=$url.$val; }
echo $target."rn";

> Finally Take out the file name, which is 1.gif in /img/1.gif, and use it to save the file.

if (!is_file('./img/'.$name[1])) {
$imgc = file_get_contents($target);
$handle = fopen('./img/'.$ name[1],'w+');
fwrite($handle,$imgc);
fclose($handle);
}

>One time, Xiaoxie suddenly discovered the power of Copy. > Copy can actually be downloaded, so you can easily use the following code to handle it, and the above one can retire the bird.

if (!is_file('./img/'.$name[1])) {
copy($target,'./img/'.$name[1]);
}

5. Complete source code: Just fill in $url when using it, and then save all CSS content to abc.css.

$url = 'http://bbs.it-home.org/css/';
$data = file_get_contents('abc.css');
preg_match('/( .*//.*?)//',$url,$host);
$host = $host[1];
if (!is_dir('img')) { mkdir('img'); }
 $regex = '/url('{0,1}"{0,1}(.*?)'{0,1}"{0,1})/';
preg_match_all($regex,$data,$ result);
foreach ($result[1] as $val) {
if (preg_match('/^http.*/',$val)) { $target = $val; }
else if (preg_match('/ ^/.*/',$val)) { $target=$host.$val; }
else { $target=$url.$val; }
echo $target."rn";
preg_match('/.*/(.*.D+)$/',$val,$name);
if (!is_file('./img/'.$name[1])) {
copy($ target,'./img/'.$name[1]);
}
