PHP发送HTTP请求的6种方法，知道4种算你牛！
方法1: 用 file_get_contents 以get方式获取内容：
<?发法知php $url=https://wenda.shukaiming.com/; echo file_get_contents($url); ?>方法2: 用fopen打开url, 以get方式获取内容：
<?php //r标识read，即标识只读 $fp = fopen($url,送H算牛 r); stream_get_meta_data($fp); while(!feof($fp)) { $body.= fgets($fp, 1024); } echo $body; fclose($fp); ?>方法3：用 file_get_contents函数,以post方式获取url
<?php $data = array (‘foo => ‘bar); $data = http_build_query($data); $opts = array ( http => array ( method => POST, header=> Content-type: application/x-www-form-urlencodedrn . Content-Length: . strlen($data) . \r\n, content => $data ) ); $context = stream_context_create($opts); $html = file_get_contents(https://wenda.shukaming.com, false, $context); echo $html; ?>方法4：用fsockopen函数打开url，以get方式获取完整的请求数据，包括header和body,种方fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启
<?php function get_url ($url,$cookie=false) { $url = parse_url($url); $query = $url[path].”?”.$url[query]; echo $query; $fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30); if (!$fp) { return false; } else { $request = "GET $query HTTP/1.1\r\n"; $request .= "Host: $url[host]\r\n"; $request .= "Connection: Close\r\n"; if($cookie) $request.="Cookie: $cookien"; $request.="\r\n"; fwrite($fp,$request); while(!@feof($fp)) { $result .= @fgets($fp, 1024); } fclose($fp); return $result; } } //获取url的云南idc服务商html部分，去掉header function GetUrlHTML($url,道种$cookie=false) { $rowdata = get_url($url,$cookie); if($rowdata) { $body= stristr($rowdata,”rnrn”); $body=substr($body,4,strlen($body)); return $body; } return false; } ?>方法5：用fsockopen函数打开url，以POST方式获取完整的发法知数据，IT技术网包括header和body
<?送H算牛php function HTTP_Post($URL,$data,$cookie, $referrer="") { // parsing the given URL $URL_Info=parse_url($URL); // Building referrer if($referrer=="") // if not given use this script as referrer $referrer="111"; // making string from $data foreach($data as $key=>$value) $values[]="$key=".urlencode($value); $data_string=implode("&",$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/1.1\n"; $request.="Host: ".$URL_Info["host"]."\n"; $request.="Referer: $referer\n"; $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; } ?>方法6:使用curl库，使用curl库之前，请求可能需要查看一下php.ini是种方否已经打开了curl扩展
<?php $ch = curl_init(); $timeout = 5; curl_setopt ($ch, CURLOPT_URL, http://wenda.shukaiming.com); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents; ?> 亿华云计算本文地址：http://www.bhae.cn/html/81f4699872.html
