$html = file_get_contents($url);
2、 用fopen打开url, 以get方式获取内容
示例:
$fp = fopen($url, 'r'); $html = stream_get_meta_data($fp);
3、用 file_get_contents函数,以post方式获取url
$data = array ('test' => 'hellword'); $data = http_build_query($data); $opts = array ( 'http' => array ( 'method' => 'POST', 'header'=> "Content-type: application/x-www-form-urlencoded\r\n" . "Content-Length: " . strlen($data) . "\r\n", 'content' => $data ), ); $context = stream_context_create($opts); $html = file_get_contents($url, false, $context);
4、使用curl库,使用 curl库之前,需先确认有打开curl扩展
$ch = curl_init(); $timeout = 5; curl_setopt ($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents;
