PHPからPOSTリクエストを送信する三つの方法

サンプルコード:

class Request{
  //方法1 curl
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;

}

//方法2 file_get_content関数を利用する
public static function post2($url, $data){//file_get_content

$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, false, $context);

return $result;

}

 //方法3 fsocket 関数を利用
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;

}
}
