使用cURL从页面下载并保存图像

Posted 2021-02-23

Here is a set of functions that can be very useful: Give this script the url of a webpage, and it will save all images from this page on your server.

function getImages($html) {
    $matches = array();
    $regex = '~http://somedomain.com/images/(.*?).jpg~i';
    preg_match_all($regex, $html, $matches);
    foreach ($matches[1] as $img) {
        saveImg($img);
    }
}
 
function saveImg($name) {
    $url = 'http://somedomain.com/images/'.$name.'.jpg';
    $data = get_data($url);
    file_put_contents('photos/'.$name.'.jpg', $data);
}
 
$i = 1;
$l = 101;
 
while ($i < $l) {
    $html = get_data('http://somedomain.com/id/'.$i.'/');
    getImages($html);
    $i += 1;
}
