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().

本文实例讲述了php使用fsockopen函数发送post,get请求获取网页内容的方法。分享给大家供大家参考。

复制代码 代码如下:$post =1; $url =
parse_url; $host =’//www.jb51.net’; $path =’/’; $query
=’?action=phpfensi.com’; $port =80; if { $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.” “; $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 {
return ”;//note $errstr : $errno } else { return ‘成功访问’;
}fsockopen语法:复制代码 代码如下:resource
fsockopen(string $hostname [,int $port = -1 [, int &$errno [,string
&$errstr [, float $timeout = ini_get(“default_socket_timeout”)
]]]] )

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:复制代码 代码如下:$fp =
fsockopen(“www.jb51.net”, 80, $errno, $errstr, 30); if { echo “$errstr
“; } else { $out = “get / http/1.1 “; $out .= “host: www.jb51.net”; $out
.= “connection: close “; fwrite; while { echo fgets; } fclose; }

希望本文所述对大家的PHP程序设计有所帮助。
