可以用正?提取。
$url = "http://www.mafengwo.cn/yj/10206/2-0-1.html";
$opts = array(
'http'=>array(
'timeout'=>10,
'header'=>"User-Agent: php\r\n" .
"Cookie: foo=bar\r\n"
)
);
$context = stream_context_create($opts);
$data = file_get_contents($url,false,$context)
这样可以读取到页面
可以用正?提取。
正则不会啊
没关系,加一个上下文(context)就可以了
include 'simple_html_dom.php';$opts = array( 'http'=>array( 'user_agent' => $_SERVER['HTTP_USER_AGENT'] ) ); $context = stream_context_create($opts); $url = 'http://www.mafengwo.cn/yj/10206/2-0-1.html';$html = file_get_html($url, false, $context);

嗯嗯,现在出来了, 输出出来的是上边的内容,但是我区分不出来了,不会用正则把信息分开了
不至于吧?
include 'simple_html_dom.php';$opts = array( 'http'=>array( 'user_agent' => $_SERVER['HTTP_USER_AGENT'] ) ); $context = stream_context_create($opts); $url = 'http://www.mafengwo.cn/yj/10206/2-0-1.html'; $html = file_get_html($url, false, $context);$div = $html->find('div.post-list ul');foreach($div[0]->find('li') as $i=>$item) { echo $item->find('img')[0]->src, PHP_EOL; echo trim($item->find('h2')[0]->text()), PHP_EOL; echo trim($item->find('div')[3]->text()), PHP_EOL; //echo '**', $item->innertext(), PHP_EOL;}
