如何将 CURL 和 PHP Simple HTML DOM Parser 与对象一起使用

Question

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);

?>

Result

Answer 1

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 );

Check the Manual for more details...

Edit

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

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);

Curl will return a string containing the HTML right? Just use the quick start sample ?

$html = str_get_html(curl_exec($ch));
