php使用curl上传文件

function uploadFile($strUrl, $strSrcFilePath, $arrPostParam, $arrCookie=array(), $strReferer='')
{
	$arrParam = array(
		'object_file' => '@'.$strSrcFilePath,
	);
	$arrParam = array_merge($arrPostParam, $arrParam);
	$ch = curl_init($strUrl);
	curl_setopt($ch, CURLOPT_HEADER, 0);

	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

	curl_setopt($ch, CURLOPT_MAXREDIRS, 3);
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
	curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
	if ($arrCookie && is_array($arrCookie)) {
		$cookie_str = '';
		foreach($arrCookie as $key => $value) {
			$cookie_str .= "$key=$value; ";
		}
		curl_setopt($ch, CURLOPT_COOKIE, $cookie_str);
	}
	$response = curl_exec($ch);
	if (curl_errno($ch) != 0) {
		return array('errno'=>1, 'errmsg'=>"upload $strSrcFilePath failed: ".curl_error($ch), 'data'=>'');
	}
	curl_close($ch);
