php4 용 소켓통신..(agent,cookie 추가)

네이버 api작업하다 필요해서만든 소켓통신함수...

호스팅 환경이 php4다보니 이것저것 함수에 제한이 좀 있어서 검색한거에 
내가 쓸만하게끔 변경함..

- GET,POST,다른포트, ssl도 그냥 되도록 만듬. http1.0이용
- http1.1에선 추가할헤더나 데이터에 이상한값문제로 보류함.
- http_build_query 가지원안되는 버젼에서는 함수를 생성하도록함.

[사용]

$_url = "http://openapi.naver.com/search";
$_send_data = array(
              'key'=> API_KEY
              ,'target' => "recmd"
              ,'query' => iconv("euc-kr","utf-8",$sch_key)
);
$_return_data = get_socket($_url, $_send_data,"GET");

결과값은 배열로 리턴
return array(
         'status' => 'ok' //실행결과
         ,'header' => $header  //받은헤더
         ,'content' => $content  // 받은데이터
        ,'urls' => $path //접속url
);

[2014-04 추가] agent, cookie 부분추가.

사용
- 로그인이 필요한 경우나 cookie가 필요한경우 최초 접속시 생성된 쿠키를 변수에 담아두고 이후 재사용
- AGENT 는 필요한 경우에 셋팅
---------------------------------------------------------------------
1. 로그인시 또는 최초접속

$_url = "로그인url";
$_set = array(
    'return_type'=> 'json'
    ,'userid'=> $_uid
    ,'userpasswd'=> $_pw
);
$_res = get_socket($_url,$_set,'POST','',AGENT);
$_result = $_res['status'];
if( $_result == 'ok'){
    preg_match_all("/Set-Cookie: [^\n]+/", $_res['header'], $_cook);
    $_cookies = array();
    foreach($_cook[0] AS $_V){
        $_tmp = explode(";",$_V);
        $_tmp1 = explode("=",str_replace('Set-Cookie: ','',$_tmp[0]));
        $_cookies[$_tmp1[0]] = $_tmp1[1];
    }
}
-------------------------------------------------------------------------
2. 이후 계속 쿠키를 재사용 
$_url = "작업url";
$_set = array(
    'return_type'=> 'json'
);
$_res = get_socket($_url,$_set,'GET','',AGENT,$_cookies);
$_result = $_res['status'];
if( $_result == 'ok'){
    blah blah~~~
}else{
    blah blah~~~
}

$port = $url['port'];
if(!$port){$port=80;}
// open a socket connection on port 80 - timeout: 30 sec

while(!feof($fp)) {
// receive the results of the request
$result .= fgets($fp, 128);
}
}else {
return array(
'status' => 'err',
'error' => "$errstr ($errno)"
);
}
@fclose($fp);
//die($result);
// split the result header from the content
$result_post = explode("\r\n\r\n", $result, 2);
