本篇文章主要介绍PHP中socket如何发送HTTP请求，感兴趣的朋友参考下，希望对大家有所帮助。
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($socket, 'www.baidu.com', 80);//里面的换行代表 \r\n 注意拷贝的代码后面可能有空格$http = <<<eofGET / HTTP/1.0Accept: */*User-Agent: Lowell-AgentHost: www.baidu.comConnection: Closeeof;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/1.1\r\n"; $out .= "Host: www.baidu.com\r\n"; $out .= "Connection: Close\r\n\r\n"; fwrite($fp, $http); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp);}
stream 方式（get）：
$http = <<<eofHost: www.baidu.comUser-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8Accept-Language: zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3Cookie: BAIDUID=79D98B1AD8436C57B967E111E484F1CD:FG=1; BDUSS=lF-UFFOanFPVG92NmF4U3NiTEoxOFh4YVBCTnZaMUtoTUNhZmxrWThwN25IaUJVQVFBQUFBJCQAAAAAAAAAAAEAAADzo1gKc2lxaW5pYW8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAOeR-FPnkfhTU; BAIDUPSID=79D98B1AD8436C57B967E111E484F1CD; BD_UPN=13314352; BD_HOME=1; H_PS_PSSID=10047_1435_10874_10212_10501_10496_10753_10796_10219_10355_10666_10597_10095_10658_10442_10700_10460_10360_10618; sug=3; sugstore=0; ORIGIN=2; bdime=0Connection: keep-aliveCache-Control: max-age=0eof;$hdrs = array( 'http' =>array( 'header' => $http, 'timeout'=>1, //超时 秒 'method' => 'GET', //默认方式 'protocol_version' <div>）本文来源gaodai.ma#com搞#代!码网_</div><strong>搞代gaodaima码</strong>=> '1.1', //默认为 1.0 ),);$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 = <<<eofHost: www.baidu.comUser-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8Accept-Language: zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3Content-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=0Connection: keep-aliveCache-Control: max-age=0eof;#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' => $postdata, 'protocol_version' => '1.1', //默认为 1.0 ),);$context = stream_context_create($hdrs);echo file_get_contents('http://test.cm/song.php', 0, $context);
