你想使用HTML/DOM解析器對於這一點，這是不爲正則表達式或字符串搜索工作。

我喜歡PHP的DOMDocument，這不是太難用了。

$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'); 
}
