Question

我的经度和纬度存储在我的数据库中。
是否有任何可以传递值和获取位置的函数。

Answer 1

试试这个希望这会对你有所帮助

function get_location($lat, $lon) {

        $url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=" .
                $lat . "," . $lon . "&sensor=false";

        $json = @file_get_contents($url);
        $data = json_decode($json);

        $status = $data->status;
        $address = '';

        if ($status == "OK") {

            $address = $data->results[0]->formatted_address;
            return $address;
        } else
            return '';
    }

echo get_location($lat, $lon); //function call

Answer 2

如果我理解正确，您可以为访客存储纬度和经度。为了获得具有这些值的地址，您需要使用第三方API来反转地理编码＆＃34;位置。

有些选择是：

- Google的地理编码服务

- Mapbox的API

- OSM也可以有一些东西。

您可以使用curl之类的内容来查询这些API 来自Mapbox网站的示例

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://api.mapbox.com/geocoding/v5/mapbox.places/-73.989,40.733.json?access_token=your-access-token",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_CUSTOMREQUEST => "GET",
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

以下是我发现使用http://ipinfodb.com/ip_locator.php获取其信息的代码段的修改版本。请注意，您也可以使用它们申请API密钥，并直接使用API获取您认为合适的信息。正如您所看到的http://ipinfodb.com/ip_location_api.php，它们包含从PHP到JavaScript到ASP.Net的所有示例。如上所述，下面不需要密钥，因为它通过页面提取公共页面和正则表达式以获取指定信息。 Key是免费的。

段

function detect_location($ip=NULL, $asArray=FALSE) {
    if (empty($ip)) {
        if (!empty($_SERVER['HTTP_CLIENT_IP'])) { $ip = $_SERVER['HTTP_CLIENT_IP']; }
        elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; }
        else { $ip = $_SERVER['REMOTE_ADDR']; }
    }
    elseif (!is_string($ip) || strlen($ip) < 1 || $ip == '127.0.0.1' || $ip == 'localhost') {
        $ip = '8.8.8.8';
    }

    $url = 'http://ipinfodb.com/ip_locator.php?ip=' . urlencode($ip);
    $i = 0; $content; $curl_info;

    while (empty($content) && $i < 5) {
        $ch = curl_init();
        $curl_opt = array(
            CURLOPT_FOLLOWLOCATION => 1,
            CURLOPT_HEADER => 0,
            CURLOPT_RETURNTRANSFER  => 1,
            CURLOPT_URL => $url,
            CURLOPT_TIMEOUT => 1,
            CURLOPT_REFERER => 'http://' . $_SERVER['HTTP_HOST'],
        );
        if (isset($_SERVER['HTTP_USER_AGENT'])) $curl_opt[CURLOPT_USERAGENT] = $_SERVER['HTTP_USER_AGENT'];
        curl_setopt_array($ch, $curl_opt);
        $content = curl_exec($ch);
        if (!is_null($curl_info)) $curl_info = curl_getinfo($ch);
        curl_close($ch);
    }

    $araResp = array();
    if (preg_match('{<li>City : ([^<]*)</li>}i', $content, $regs)) $araResp['city'] = trim($regs[1]);
    if (preg_match('{<li>State/Province : ([^<]*)</li>}i', $content, $regs)) $araResp['state'] = trim($regs[1]);
    if (preg_match('{<li>Country : ([^<]*)}i', $content, $regs)) $araResp['country'] = trim($regs[1]);
    if (preg_match('{<li>Zip or postal code : ([^<]*)</li>}i', $content, $regs)) $araResp['zip'] = trim($regs[1]);
    if (preg_match('{<li>Latitude : ([^<]*)</li>}i', $content, $regs)) $araResp['latitude'] = trim($regs[1]);
    if (preg_match('{<li>Longitude : ([^<]*)</li>}i', $content, $regs)) $araResp['longitude'] = trim($regs[1]);
    if (preg_match('{<li>Timezone : ([^<]*)</li>}i', $content, $regs)) $araResp['timezone'] = trim($regs[1]);
    if (preg_match('{<li>Hostname : ([^<]*)</li>}i', $content, $regs)) $araResp['hostname'] = trim($regs[1]);

    $strResp = ($araResp['city'] != '' && $araResp['state'] != '') ? ($araResp['city'] . ', ' . $araResp['state']) : 'UNKNOWN';

    return $asArray ? $araResp : $strResp;
}

使用

detect_location();
//  returns "CITY, STATE" based on user IP

detect_location('xxx.xxx.xxx.xxx');
//  returns "CITY, STATE" based on IP you provide

detect_location(NULL, TRUE);    //   based on user IP
//  returns array(8) { ["city"] => "CITY", ["state"] => "STATE", ["country"] => "US", ["zip"] => "xxxxx", ["latitude"] => "xx.xxxxxx", ["longitude"] => "-xx.xxxxxx", ["timezone"] => "-07:00", ["hostname"] => "xx-xx-xx-xx.host.name.net" }

detect_location('xxx.xxx.xxx.xxx', TRUE);   //   based on IP you provide
//  returns array(8) { ["city"] => "CITY", ["state"] => "STATE", ["country"] => "US", ["zip"] => "xxxxx", ["latitude"] => "xx.xxxxxx", ["longitude"] => "-xx.xxxxxx", ["timezone"] => "-07:00", ["hostname"] => "xx-xx-xx-xx.host.name.net" }

        $result = new static;
        foreach($data as $key => $val) {
            $result->$key = $val;
        }
        return $result;

            return xcache_get($q_hash);
        }
        if(is_callable('curl_init')) {
            $c = curl_init();
            curl_setopt($c, CURLOPT_URL, self::$api.$q.'?fields='.self::$fields);
            curl_setopt($c, CURLOPT_HEADER, false);
            curl_setopt($c, CURLOPT_TIMEOUT, 30);
            curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
            $result_array = unserialize(curl_exec($c));
            curl_close($c);
        } else {
            $result_array = unserialize(file_get_contents(self::$api.$q.'?fields='.self::$fields));
        }
        if(self::$use_xcache) {

        }
        return $result_array;
    }

// example
$query = IPAPI::query("google.com");
