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 \r\n 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/1.1\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);
    }

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-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
