您希望为此使用HTML / DOM解析器，不是正则表达式或字符串搜索的作业。

我喜欢PHP的DOMDocument，它使用起来并不太难。

$url = 'http://stackoverflow.com/questions/7994340/how-can-i-get-image-from-url-in-php-or-jquery-or-in-both';
$data = file_get_contents($url);

$dom = new DOMDocument;
// I usually say to NEVER use the "@" operator,
// but everyone's HTML isn't perfect, and this may throw warnings
@$dom->loadHTML($data);

$img = $dom->getElementsByTagName('img');
foreach($img as $x){
    echo $x->getAttribute('src');
}
