PHP code

-->$content = 
Copy after login
  • html; $parr = "/href=\"\/html5\/(.*)\"/i"; preg_match_all($parr, $content, $result); var_dump($result);
    匹配到的结果如下 
    string(30) "tag_comment.asp" title="HTML 5"
    string(15) "tag_doctype.asp"

    第一个还包含了 title 属性。 我的本意是只取href属性的值,该怎么做?

    ------解决方案--------------------
    $parr = "/href=\"\/html5\/(.*?)\"/i";



    array(2) {
    [0]=>
    array(2) {
    [0]=>
    string(29) "href="/html5/tag_comment.asp""
    [1]=>
    string(29) "href="/html5/tag_doctype.asp""
    }
    [1]=>
    array(2) {
    [0]=>
    string(15) "tag_comment.asp"
    [1]=>
    string(15) "tag_doctype.asp"
    }
    }

    ------解决方案--------------------
    我一直用这个,忘了从哪里找的了。反正我是看不懂,只管用
    PHP code
    
    '/<a.>(.+?)/sim' <div class="clear">
                     
                  
                  
            
                </div></a.>
