php发送post请求的三种方法

方法一：

$postdata = http_build_query($post_data);
$options = array(
'http' => array(
'method' => 'POST','header' => 'Content-type:application/x-www-form-urlencoded','content' => $postdata,'timeout' => 15 * 60 // 超时时间（单位:s）
)
);
$context = stream_context_create($options);
$result = file_get_contents($url,false,$context);

return $result;
}

//使用方法
$post_data = array(
'username' => 'stclair2201','password' => 'handan'
);
send_post('//www.jb51.cc',$post_data);

方法二：Socket版本

rush:PHP;"> $data = "";
while (!feof($socket)) {
$data .= fgets($socket,4096);
}

return $data;
}
?>

方法三：Curl版本

rush:PHP;"> return $data;
}
?>

下面是其他网友的方法：

$postdata = http_build_query( $data ); $opts = array('http' => array( 'method' => 'POST','header' => 'Content-type: application/x-www-form-urlencoded','content' => $postdata ) ); $context = stream_context_create($opts); $result = file_get_contents($url,$context); return $result;

}
public static function post3($host,$path,$query,$others=''){//fsocket
$post="POST $path HTTP/1.1\r\nHost: $host\r\n";
$post.="Content-type: application/x-www-form-";
$post.="urlencoded\r\n${others}";
$post.="User-Agent: Mozilla 4.0\r\nContent-length: ";
$post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";
$h=fsockopen($host,80);
fwrite($h,$post);
for($a=0,$r='';!$a;){
$b=fread($h,8192);
$r.=$b;
$a=(($b=='')?1:0);
}
fclose($h);
return $r;
}
}

大家可以根据需要选择适合自己的即可。
