php使用fsockopen函数发送post,get请求获取网页内容的方法

if($post) {
$out = "post $path http/1.0 ";
$out .= "accept: / ";
//$out .= "referer: $boardurl ";
$out .= "accept-language: zh-cn ";
$out .= "content-type: application/x-www-form-urlencoded ";
$out .= "user-agent: $_server[http_user_agent] ";
$out .= "host: $host ";
$out .= 'content-length: '.strlen($post)." ";
$out .= "connection: close ";
$out .= "cache-control: no-cache ";
$out .= "cookie: $cookie ";
$out .= $post;
} else {
$out = "get $path http/1.0 ";
$out .= "accept: / ";
//$out .= "referer: $boardurl ";
$out .= "accept-language: zh-cn ";
$out .= "user-agent: $_server[http_user_agent] ";
$out .= "host: $host ";
$out .= "connection: close ";
$out .= "cookie: $cookie ";
}
$fp = @fsockopen(($ip ? $ip : $host),$port,$errno,$errstr,$timeout);
if(!$fp)
{
return '';//note $errstr : $errno
} else {
return '成功访问';
}
fsockopen语法:<div class="codetitle"><a style="CURSOR: pointer" data="94358" class="copybut" id="copybut94358" onclick="doCopy('code94358')"> 代码如下:<div class="codebody" id="code94358">resource fsockopen(string $hostname [,int $port = -1 [,int &$errno [,string &$errstr [,float $timeout = ini_get("default_socket_timeout") ]]]] )

启动一个套接字连接到指定的主机的资源,php支持在互联网领域的目标和unix在所支持的套接字传输列表说明,所支持的传输列表也可以检索使用stream_get_transports（）.

该插座预设会被启用,阻塞模式,你可以切换到非阻塞模式使用stream_set_blocking（）,如果上面实例看不懂,就来看个简的吧,代码如下: 代码如下:
