curl request method

/**
 * 发送HTTP请求方法，目前只支持CURL发送请求
 * @param  string $url    请求URL
 * @param  array  $params 请求参数
 * @param  string $method 请求方法GET/POST
 * @return array  $data   响应数据
 */
function http($url, $params, $method = 'GET', $header = array(), $multi = false){
	$opts = array(
			CURLOPT_TIMEOUT        => 30,
			CURLOPT_RETURNTRANSFER => 1,
			CURLOPT_SSL_VERIFYPEER => false,
			CURLOPT_SSL_VERIFYHOST => false,
			CURLOPT_HTTPHEADER     => $header
	);

	/* 根据请求类型设置特定参数 */
	switch(strtoupper($method)){
		case 'GET':
			$opts[CURLOPT_URL] = $url . '?' . http_build_query($params);
			break;
		case 'POST':
			//判断是否传输文件
			//$params = $multi ? $params : http_build_query($params);
			$opts[CURLOPT_URL] = $url;
			$opts[CURLOPT_POST] = 1;
			$opts[CURLOPT_POSTFIELDS] = $params;
			break;
		default:
			throw new Exception('不支持的请求方式！');
	}

	/* 初始化并执行curl请求 */
	$ch = curl_init();
	curl_setopt_array($ch, $opts);
	$data  = curl_exec($ch);
	$error = curl_error($ch);
	curl_close($ch);
	if($error) throw new Exception('请求发生错误：' . $error);
	return  $data;
}

The above introduces the curl request method, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
