本文实例讲述了PHP封装CURL扩展类。分享给大家供大家参考。具体如下：
rush:PHP;">
ch_ = curl_init($url);
curl_setopt($this->ch_,CURLOPT_HEADER,1);
curl_setopt($this->ch_,CURLOPT_RETURNTRANSFER,1 );
}
/**
* @返回响应头

$h = explode(':',$h,2);
if (isset($h[1])) {
if(!isset($headers[$h[0]])) {
$headers[$h[0]] = trim($h[1]);
} else if(is_array($headers[$h[0]])) {
$tmp = array_merge($headers[$h[0]],array(trim($h[1])));
$headers[$h[0]] = $tmp;
} else {
$tmp = array_merge(array($headers[$h[0]]),array(trim($h[1])));
$headers[$h[0]] = $tmp;
}
}
}
return $headers;
}
}

}

}
/**

}

*/

希望本文所述对大家的PHP程序设计有所帮助。
