以下方法可以实现将 POST 值发送到 url，并获取返回值

$url = 'http://www.someurl.com';
$myvars = 'myvar1=' . $myvar1 . '&myvar2=' . $myvar2;

$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $myvars);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, );
curl_setopt( $ch, CURLOPT_HEADER, );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, );

$response = curl_exec( $ch );
