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_TIMEOUT, 5);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $arrParam);
    curl_setopt($ch, CURLOPT_REFERER, $strReferer);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 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($ch);
    if (!$response) {
