php的get、post请求

get post请求出现的一些乱码
直接上代码，一看便知

/**
 * get 请求
 * @param string $url 提交地址
 */
function curl_get($url = '', $header=[]){
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_HEADER, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    if ($header)
    {
        curl_setopt($curl, CURLOPT_HEADER, 0);
        curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
    }
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($curl, CURLOPT_SSLVERSION, 1);
//        $data = json_decode(curl_exec($curl), true);
    $data = curl_exec($curl);
    curl_close($curl);
    $data=mb_convert_encoding($data, 'UTF-8', 'UTF-8,GBK,GB2312,BIG5');
    return $data;
}
