php実現のCurlパッケージ類Curl.class.php用法例分析

本論文では、php実装CurlパッケージクラスCurlについて説明する.class.phpの使い方.皆さんの参考にしてください.具体的には以下の通りです.

 $val){
     $sets[] = $key . '=' . urlencode($val);
    }
    $fields = implode('&',$sets);
   }
   curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
  }else if('put' == $method){
   curl_setopt($ch, CURLOPT_PUT, true);
  }
  //curl_setopt($ch, CURLOPT_PROGRESS, true);
  //curl_setopt($ch, CURLOPT_VERBOSE, true);
  //curl_setopt($ch, CURLOPT_MUTE, false);
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);//  curl    
  if(strlen($userAgent)){
   curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
  }
  if(is_array($httpHeaders)){
   curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);
  }
  $ret = curl_exec($ch);
  if(curl_errno($ch)){
   curl_close($ch);
   return array(curl_error($ch), curl_errno($ch));
  }else{
   curl_close($ch);
   if(!is_string($ret) || !strlen($ret)){
    return false;
   }
   return $ret;
  }
 }
 function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
  $ret = Curl::execute('POST', $url, $fields, $userAgent, $httpHeaders, $username, $password);
  if(false === $ret){
   return false;
  }
  if(is_array($ret)){
   return false;
  }
  return $ret;
 }
 function get($url, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
  $ret = Curl::execute('GET', $url, '', $userAgent, $httpHeaders, $username, $password);
  if(false === $ret){
   return false;
  }
  if(is_array($ret)){
   return false;
  }
  return $ret;
 }
 function create(){
  $ch = null;
  if(!function_exists('curl_init')){
   return false;
  }
  $ch = curl_init();
  if(!is_resource($ch)){
   return false;
  }
  return $ch;
 }
}
?>

GETの使い方:

$curl = new Curl();
$curl->get('http://www.XXX.com/');

POST使用法:

$curl = new Curl();
$curl->get('http://www.XXX.com/', 'p=1&time=0');

本稿で述べたphpプログラム設計に役立つことを願っています.
