 public static function post($url, $post_data = '', $timeout = 5){//curl

 $ch =curl_init();

 curl_setopt ($ ch, CURLOPT_URL, $url);

 curl_setopt ($ch, CURLOPT_POST, 1);

 if($post_data != ''){

 curl_setopt($ch, CURLOPT_POSTFIELDS, $ post_data);

 }

 curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

 curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

 curl_setopt($ch, CURLOPT_HEADER, false);

 $file_contents =curl_exec($ch);

 curl_close($ch);

 return $file_contents;

 }


 public static function post2($url, $data){//file_get_content



 $postdata = http_build_query(

 $data

 );



 $opts = array('http' =>

 array(

 'メソッド' => 'POST',

 ' header' => 'Content-type: application/x-www-form-urlencoded',

 'content' => ; $postdata

 )

 );



 $context = stream_context_create($opts);


 $result = file_get_contents($url, false, $context);

 return $result;


 }


 public static function post3($host,$path,$query,$others=''){//fsocket


 $post="POST $path HTTP/1.1rnHost: $hostrn";

 $post .="Content-type: application/x-www-form-";

 $post.="urlencodedrn${others}";

 $post.="User-Agent: Mozilla 4.0rnContent-length: ";

 $post.=strlen($query)."rnConnection: closenrn$query";

 $h=fsockopen($host,80);

 fwrite($h,$post);

 for($a =0,$r='';!$a;){

 $b=fread($h,8192);

 $r.=$b;

 $a=(($b=='' )?1:0);
