使用PHP获取img src

使用类似的HTML解析器

DOMdocument

DOMXpath

$html = '<img id="12" border="0" src="/images/image.jpg"         alt="Image" width="100" height="100" />';$doc = new DOMdocument();$doc->loadHTML($html);$xpath = new DOMXPath($doc);$src = $xpath->evaluate("string(//img/@src)"); # "/images/image.jpg"

或对于那些确实需要节省空间的人：

$xpath = new DOMXPath(@DOMdocument::loadHTML($html));$src = $xpath->evaluate("string(//img/@src)");

对于那里的一线客：

$src = (string) reset(simplexml_import_dom(DOMdocument::loadHTML($html))->xpath("//img/@src"));
