问题描述

使用CURL从网站获取内容.在对象中获得响应.如何将该对象转换为PHP简单HTML DOM解析器

Using CURL to get content from website. Getting response in object. How to convert that object in to PHP Simple HTML DOM Parser

function get_data($url) 
{
    $ch = curl_init();
    $timeout = 30;
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,false);
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
    curl_setopt($ch,CURLOPT_POST,false);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:10.0) Gecko/20100101 Firefox/10.0");
    //curl_exec($ch);
    $dom = new simple_html_dom(curl_exec($ch));
    print_r( $dom );
    curl_close($ch);
    return $data;
}
$url = 'http://www.example.com';
$data = get_data($url);

?>

结果

simple_html_dom Object ( [root] => simple_html_dom_node Object ( [nodetype] => 5 [tag] => root [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( [0] => simple_html_dom_node Object ( [nodetype] => 3 [tag] => text [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( ) [parent] => simple_html_dom_node Object *RECURSION* [_] => Array ( [4] => 1 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) ) [parent] => [_] => Array ( [0] => -1 [1] => 2 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) [nodes] => Array ( [0] => simple_html_dom_node Object ( [nodetype] => 5 [tag] => root [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( [0] => simple_html_dom_node Object ( [nodetype] => 3 [tag] => text [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( ) [parent] => simple_html_dom_node Object *RECURSION* [_] => Array ( [4] => 1 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) ) [parent] => [_] => Array ( [0] => -1 [1] => 2 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) [1] => simple_html_dom_node Object ( [nodetype] => 3 [tag] => text [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( ) [parent] => simple_html_dom_node Object ( [nodetype] => 5 [tag] => root [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( [0] => simple_html_dom_node Object *RECURSION* ) [parent] => [_] => Array ( [0] => -1 [1] => 2 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) [_] => Array ( [4] => 1 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) ) [callback] => [lowercase] => 1 [original_size] => 1 [size] => 1 [pos:protected] => 1 [char:protected] => [cursor:protected] => 2 [parent:protected] => simple_html_dom_node Object ( [nodetype] => 5 [tag] => root [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( [0] => simple_html_dom_node Object ( [nodetype] => 3 [tag] => text [attr] => Array ( ) [children] => Array ( ) [nodes] => Array ( ) [parent] => simple_html_dom_node Object *RECURSION* [_] => Array ( [4] => 1 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) ) [parent] => [_] => Array ( [0] => -1 [1] => 2 ) [tag_start] => 0 [dom:private] => simple_html_dom Object *RECURSION* ) [token_blank:protected] => [token_equal:protected] => =/> [token_slash:protected] => /> [token_attr:protected] => > [_charset] => UTF-8 [_target_charset] => UTF-8 [default_br_text:protected] => [default_span_text] => [self_closing_tags:protected] => Array ( [img] => 1 [br] => 1 [input] => 1 [meta] => 1 [link] => 1 [hr] => 1 [base] => 1 [embed] => 1 [spacer] => 1 ) [block_tags:protected] => Array ( [root] => 1 [body] => 1 [form] => 1 [div] => 1 [span] => 1 [table] => 1 ) [optional_closing_tags:protected] => Array ( [tr] => Array ( [tr] => 1 [td] => 1 [th] => 1 ) [th] => Array ( [th] => 1 ) [td] => Array ( [td] => 1 ) [li] => Array ( [li] => 1 ) [dt] => Array ( [dt] => 1 [dd] => 1 ) [dd] => Array ( [dd] => 1 [dt] => 1 ) [dl] => Array ( [dd] => 1 [dt] => 1 ) [p] => Array ( [p] => 1 ) [nobr] => Array ( [nobr] => 1 ) [b] => Array ( [b] => 1 ) [option] => Array ( [option] => 1 ) ) [doc:protected] => 1 [noise:protected] => Array ( ) ) 

推荐答案

您没有正确创建DOM，您必须这样做:

You're not creating the DOM correctly, you must do it like this:

// Create a DOM object
$dom = new simple_html_dom();
// Load HTML from a string
$dom->load(curl_exec($ch))

print_r( $dom );

查看手册以了解更多详细信息...

Check the Manual for more details...

修改

似乎是cURL设置问题，请参考文档正确配置它...

It seems that is a cURL settings problem, please refer to the documentation to configure it correctly...

这是我通常用于下载某些页面的功能，可以根据需要进行调整:

This is a function I usualy use to download some pages, feel free to adjust it to your needs:

function dlPage($href) {

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_URL, $href);
    curl_setopt($curl, CURLOPT_REFERER, $href);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.125 Safari/533.4");
    $str = curl_exec($curl);
    curl_close($curl);

    // Create a DOM object
    $dom = new simple_html_dom();
    // Load HTML from a string
    $dom->load($str);

    return $dom;
    }

$url = 'http://www.example.com/';
$data = dlPage($url);
print_r($data);
