我正试图从特定的URL中提取所有图像，并将其存储在特定的文件夹中。我试着做了一些研究，但我只能得到一些图片列表。
<?php
// $url_image = $_GET['url'];
$url_image = 'https://www.thebridesofoklahoma.com/wedding-inspiration/elegant-yet-modern/';
$homepage = file_get_contents($url_image);
preg_match_all("{<img\s*(.*?)src=('.*?'|".*?"|[^\s]+)(.*?)\s*/?>}ims", $homepage, $matches, PREG_SET_ORDER);
// print_r($matches);
foreach ($matches as $val) {
$pos = strpos($val[2],"/");
$link = substr($val[2],1,-1);
if($pos == 1)
echo "https://www.thebridesofoklahoma.com" . $link;
else
echo $link;
echo "<br>";
}
?>
有人能帮我获取仅在画廊中使用的所有图片url列表吗。请参阅此网页：https://www.thebridesofoklahoma.com/wedding-inspiration/elegant-yet-modern/
不要使用Regex来解析HTML。使用DomDocument。可用的图像被包装到一个div中，因此使用XPath很容易找到它们。
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile('https://www.thebridesofoklahoma.com/wedding-inspiration/elegant-yet-modern/');
$img = new DOMXPath($doc);
foreach($img->query('//div/img') as $image) {
echo $image->getAttribute('src'), PHP_EOL;
}
