方法一：

/*** 發送post請求* @param string $url 請求地址* @param array $post_data post鍵值對數據* @return string*/ function send_post($url, $post_data) {$postdata = http_build_query($post_data);$options = array('http' => array('method' => 'POST','header' => 'Content-type:application/x-www-form-urlencoded','content' => $postdata,'timeout' => 15 * 60 // 超時時間（單位:s）));$context = stream_context_create($options);$result = file_get_contents($url, false, $context);return $result; }//使用方法 $post_data = array('username' => 'stclair2201','password' => 'handan' ); send_post('http://www.jb51.net', $post_data);

方法二 ?? Socket版本

<?php /*** Socket版本* 使用方法：* $post_string = "app=socket&version=beta";* request_by_socket('chajia8.com', '/restServer.php', $post_string);*/ function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30) {$socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout);if (!$socket) die("$errstr($errno)");fwrite($socket, "POST $remote_path HTTP/1.0");fwrite($socket, "User-Agent: Socket Example");fwrite($socket, "HOST: $remote_server");fwrite($socket, "Content-type: application/x-www-form-urlencoded");fwrite($socket, "Content-length: " . （strlen($post_string) + 8） . "");fwrite($socket, "Accept:*/*");fwrite($socket, "");fwrite($socket, "mypost=$post_string");fwrite($socket, "");$header = "";while ($str = trim(fgets($socket, 4096))) {$header .= $str;}$data = "";while (!feof($socket)) {$data .= fgets($socket, 4096);}return $data; } ?>
方法三 ? curl版本

<?php /*** Curl版本* 使用方法：* $post_string = "app=request&version=beta";* request_by_curl('http://www.jb51.net/restServer.php', $post_string);*/ function request_by_curl($remote_server, $post_string) {$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $remote_server);curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost=' . $post_string);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);curl_setopt($ch, CURLOPT_USERAGENT, "jb51.net's CURL Example beta");$data = curl_exec($ch);curl_close($ch);return $data; } ?>

下面是其他網友的方法：

class Request{public static function post($url, $post_data = '', $timeout = 5){//curl$ch = curl_init();curl_setopt ($ch, CURLOPT_URL, $url);curl_setopt ($ch, CURLOPT_POST, 1);if($post_data != ''){curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);}curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);curl_setopt($ch, CURLOPT_HEADER, false);$file_contents = curl_exec($ch);curl_close($ch);return $file_contents;}public static function post2($url, $data){//file_get_content$postdata = http_build_query($data);$opts = array('http' =>array('method' => 'POST','header' => 'Content-type: application/x-www-form-urlencoded','content' => $postdata));$context = stream_context_create($opts);$result = file_get_contents($url, false, $context);return $result;}public static function post3($host,$path,$query,$others=''){//fsocket$post="POST $path HTTP/1.1\r\nHost: $host\r\n";$post.="Content-type: application/x-www-form-";$post.="urlencoded\r\n${others}";$post.="User-Agent: Mozilla 4.0\r\nContent-length: ";$post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";$h=fsockopen($host,80);fwrite($h,$post);for($a=0,$r='';!$a;){$b=fread($h,8192);$r.=$b;$a=(($b=='')?1:0);}fclose($h);return $r;} }

對于遠程請求，有很多種方法。今天，LZ就搜羅了六種，供大家參考。

1、用file_get_contents 以get方式獲取內容：

<?php $url='http://www.ido321.com/'; $html = file_get_contents($url); echo $html; ?>

?

?? 2、用fopen打開url，用get方式獲取

$fp = fopen($url, 'r'); stream_get_meta_data($fp); while(!feof($fp)) { $result .= fgets($fp, 1024); } echo "url body: $result"; fclose($fp);

?

?

3、用file_get_contents 以post方式獲取內容：

$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) . '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函數打開url，以get方式獲取完整的數據，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 選項開啟

function get_url ($url,$cookie=false) { $url = parse_url($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 $result; } } //獲取url的html部分，去掉header function GetUrlHTML($url,$cookie=false) { $rowdata = get_url($url,$cookie); if($rowdata) { $body= stristr($rowdata,'rnrn'); $body=substr($body,4,strlen($body)); return $body; }return false; }

?

?

???? 5、用fsockopen函數打開url，以POST方式獲取完整的數據，包括header和body

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/1.1n"; $request.="Host: ".$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庫，使用curl庫之前，可能需要查看一下php.ini是否已經打開了curl擴展

$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;
