php 常用函数获取用户IP、curl请求

获取用户ID

/**
     * @return array|mixed|string|string[]
     */
    public function getClientIP()
    {
        if (@$_SERVER["HTTP_ALI_CDN_REAL_IP"]) {
            $ip = $_SERVER["HTTP_ALI_CDN_REAL_IP"];
        } elseif (@$_SERVER["HTTP_X_FORWARDED_FOR"] ?: false) {
            $ips = explode(',', $_SERVER["HTTP_X_FORWARDED_FOR"]);
            $ip = $ips[0];
        } elseif (@$_SERVER["HTTP_CDN_SRC_IP"] ?: false) {
            $ip = $_SERVER["HTTP_CDN_SRC_IP"];
        } elseif (getenv('HTTP_CLIENT_IP')) {
            $ip = getenv('HTTP_CLIENT_IP');
        } elseif (getenv('HTTP_X_FORWARDED')) {
            $ip = getenv('HTTP_X_FORWARDED');
        } elseif (getenv('HTTP_FORWARDED_FOR')) {
            $ip = getenv('HTTP_FORWARDED_FOR');
        } elseif (getenv('HTTP_FORWARDED')) {
            $ip = getenv('HTTP_FORWARDED');
        } else {
            $ip = $_SERVER['REMOTE_ADDR'];
        }

        $ip = str_replace(['::ffff:', '[', ']'], ['', '', ''], $ip);
        return $ip;
    }

 

curl请求

/**
     * @param $url
     * @param $data
     * @param $header
     * @param $timeout
     * @return bool|string
     */
    public function gpCurl($url, $data = '', $header = [], $timeout = 30)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        if ($header) {
            curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
        }else{
            curl_setopt($ch, CURLOPT_HEADER, 0);
        }
        if($data){
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        }
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        $result = curl_exec($ch);
        curl_close($ch);

        return $result;
    }
