本文实例讲述了PHP获取网页所有连接的方法。分享给大家供大家参考，具体如下：
function getHtml($url, $charset='utf-8') { $curl = curl_init(); //curl_setopt($curl, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:192.168.168.1', 'CLIENT-IP:192.168.168.1'));//IP curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_REFERER, ""); //来路 $user_agent = isset($_SERVER['HTTP_USER_AGENT']) ? $_SERVER['HTTP_USER_AGENT'] : 'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.43 Safari/537.31'; curl_setopt($curl, CURLOPT_USERAGENT, $user_agent); // 只需返回HTTP header // curl_setopt($curl, CURLOPT_HEADER, 1); // 页面内容我们并不需要 // curl_setopt($curl, CURLOPT_NOBODY, 1); // 返回结果，而不是输出它 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $html = curl_exec($curl); //$info = curl_getinfo($curl); //echo var_dump($info); if ($html === false) { //echo "cURL Error: " . curl_error($ch); return ''; } curl_close($curl); if ($charset != 'utf-8') { $html = iconv($charset, "UTF-8", $html); } return $html; } header("Content-type: text/html; charset=utf-8"); include('simple_html_dom.php'); // 要打开 extension=php_mbstring.dll //$url = 'http://www.baidu.com/s?wd=kaka'; $url = 'http://www.163.com/'; $str_html = getHtml($url, 'gbk'); $html = str_get_html($str_html); $links = $html->find('a'); foreach($links as $link) { $txt = trim($link->plaintext); echo $link->href . '[' . $txt . ']<br>'; } $html = null;
