本文实例讲述了PHP使用socket发送HTTP请求的方法。分享给大家供大家参考，具体如下：

socket方式：

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); //socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO, array("sec"=>20, "usec"=>0)); socket_connect($socket, 'www.baidu.com', 80); //里面的换行代表 rn 注意拷贝的代码后面可能有空格 $http = <<<eof GET / HTTP/1.0 Accept: */* User-Agent: Lowell-Agent Host: www.baidu.com Connection: Close eof; socket_write($socket, $http, strlen($http)); while($str = socket_read($socket, 1024)) { echo $str; } socket_close($socket);

fsockopen方式：

$fp = fsockopen("www.baidu.com", 80, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />n"; } else { $out = "GET / HTTP/1.1rn"; $out .= "Host: www.baidu.comrn"; $out .= "Connection: Closernrn"; fwrite($fp, $http); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); }

原始socket方式：

$fp = stream_socket_client("tcp://www.baidu.com:80", $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />n"; } else { $http = <<<eof GET / HTTP/1.0 Accept: */* User-Agent: Lowell-Agent Host: www.baidu.com Connection: Close eof; fwrite($fp, $http); while (!feof($fp)) { echo fgets($fp, 1024); } fclose($fp); }

stream 方式（get）：

$http = <<<eof Host: www.baidu.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3 Cookie: BAIDUID=79D98B1AD8436C57B967E111E484F1CD:FG=1; BDUSS=lF-UFFOanFPVG92NmF4U3NiTEoxOFh4YVBCTnZaMUtoTUNhZmxrWThwN25IaUJVQVFBQUFBJCQAAAAAAAAAAAEAAADzo1gKc2lxaW5pYW8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAOeR-FPnkfhTU; BAIDUPSID=79D98B1AD8436C57B967E111E484F1CD; BD_UPN=13314352; BD_HOME=1; H_PS_PSSID=10047_1435_10874_10212_10501_10496_10753_10796_10219_10355_10666_10597_10095_10658_10442_10700_10460_10360_10618; sug=3; sugstore=0; ORIGIN=2; bdime=0 Connection: keep-alive Cache-Control: max-age=0 eof; $hdrs = array( 'http' =>array( 'header' => $http, 'timeout'=>1, //超时 秒 'method' => 'GET', //默认方式 'protocol_version' => '1.1', //默认为 1.0 ), ); //参数格式参考 http://php.net/manual/zh/context.http.php //curl方式的格式可以参考； http://php.net/manual/zh/context.curl.php $context = stream_context_create($hdrs); echo file_get_contents('http://www.baidu.com', 0, $context);

stream 方式 post:

$postdata = http_build_query(array('act'=>'save', 'id'=>387171)); $http = <<<eof Host: www.baidu.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3 Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Cookie: BAIDUID=79D98B1AD8436C57B967E111E484F1CD:FG=1; BDUSS=lF-UFFOanFPVG92NmF4U3NiTEoxOFh4YVBCTnZaMUtoTUNhZmxrWThwN25IaUJVQVFBQUFBJCQAAAAAAAAAAAEAAADzo1gKc2lxaW5pYW8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAOeR-FPnkfhTU; BAIDUPSID=79D98B1AD8436C57B967E111E484F1CD; BD_UPN=13314352; BD_HOME=1; H_PS_PSSID=10047_1435_10874_10212_10501_10496_10753_10796_10219_10355_10666_10597_10095_10658_10442_10700_10460_10360_10618; sug=3; sugstore=0; ORIGIN=2; bdime=0 Connection: keep-alive Cache-Control: max-age=0 eof; #注意post方式需要增加Content-Type $hdrs = array( 'http' =>array( 'header' => $http, 'timeout'=>1, //超时 秒 'method' => 'POST', 'content' => $postdata, 'protocol_version' => '1.1', //默认为 1.0 ), ); //参数格式参考 http://php.net/manual/zh/context.http.php //curl方式的格式可以参考； http://php.net/manual/zh/context.curl.php $context = stream_context_create($hdrs); echo file_get_contents('http://test.cm/song.php', 0, $context);

注意：http1.1 中必须包含 Host 头， 而 http1.0中则可以没有

希望本文所述对大家PHP程序设计有所帮助。
