思齐_ 人气:0想了解PHP使用socket发送HTTP请求的方法的相关内容吗，思齐_在本文为您仔细讲解PHP socket发送HTTP请求的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：PHP,socket,HTTP请求，下面大家一起来学习吧。
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

eof;
$hdrs = array(
'http' =>array(

$context = stream_context_create($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

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
