Content-Length: . strlen($data) . rn, content $data ) ); $context stream_context_create($opts); $html file_get_contents(http://localhost/e/admin/test.html, false, $context); echo $html; 4、用fsockopen函数打开url以get方式获取完整的数据包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启 function get_url ($url,$cookiefalse) { $url parse_url($url); $query $url[path].?.$url[query]; echo Query:.$query; $fp fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30); if (!$fp) { return false; } else { $request GET $query HTTP/1.1rn; $request . Host: $url[host]rn; $request . Connection: Closern; if($cookie) $request.Cookie: $cookien; $request.rn; fwrite($fp,$request); while(!feof($fp)) { $result . fgets($fp, 1024); } fclose($fp); return $result; } } //获取url的html部分去掉header function GetUrlHTML($url,$cookiefalse) { $rowdata get_url($url,$cookie); if($rowdata) { $body stristr($rowdata,rnrn); $bodysubstr($body,4,strlen($body)); return $body; } return false; } 5、用fsockopen函数打开url以POST方式获取完整的数据包括header和body function HTTP_Post($URL,$data,$cookie, $referrer) { // parsing the given URL $URL_Infoparse_url($URL); // Building referrer if($referrer) // if not given use this script as referrer $referrer111; // making string from $data foreach($data as $key$value) $values[]$key.urlencode($value); $data_stringimplode(,$values); // Find out which port is needed – if not given use standard (80) if(!isset($URL_Info[port])) $URL_Info[port]80; // building POST-request: $request.POST .$URL_Info[path]. HTTP/1.1n; $request.Host: .$URL_Info[host].n; $request.Referer: $referern; $request.Content-type: application/x-www-form-urlencodedn; $request.Content-length: .strlen($data_string).n; $request.Connection: closen; $request.Cookie: $cookien; $request.n; $request.$data_string.n; $fp fsockopen($URL_Info[host],$URL_Info[port]); fputs($fp, $request); while(!feof($fp)) { $result . fgets($fp, 1024); } fclose($fp); return $result; } 6、使用curl库使用curl库之前可能需要查看一下php.ini是否已经打开了curl扩展 $ch curl_init(); $timeout 5; curl_setopt ($ch, CURLOPT_URL, ‘http://www.ido321.com/); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents curl_exec($ch); curl_close($ch); echo $file_contents; 来源51CTO
