在代码点火器中打印来自地理位置 API 的每个数据 - Print each data from geolocation api in codeigniter

Print each data from geolocation api in codeigniter

我想在代码点火器中打印来自地理位置API的所有信息，然后我想插入到数据库中。我尝试使用 foreach 打印，但发现错误，

    $ip='202.6x.xx.xx';
    $this->load->library('Geolocation');
    $this->load->config('geolocation', true);
    $config = $this->config->config['geolocation'];
    $this->geolocation->initialize($config);
    $this->geolocation->set_ip_address($ip);
    $country = $this->geolocation->get_country();
    //var_dump($country);
    $city = $this->geolocation->get_city();
    if($city === FALSE){
        //var_dump($this->geolocation->get_error());
    }
    else{
        //var_dump($city);
        foreach ($city as $c) {
            echo $c->regionName; <-- EROR
        }
        echo "Country code : ".$city['countryName']."'n"; <-- EROR
        echo "Cityname : ".$city['cityName']."'n";  <-- EROR
    }

这是 var_dump（$city）的值

string(286) "{ "statusCode" : "OK", "statusMessage" : "", "ipAddress" : "202.67.xx.xx", "countryCode" : "ID", "countryName" : "Indonesia", "regionName" : "regionblablabla", "cityName" : "cityblablabla", "zipCode" : "60132", "latitude" : "-7.258", "longitude" : "112.758", "timeZone" : "+07:00" }"

如果使用 foreach ：

Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: controllers/Front.php
Line Number: 105

您能否解释一下如何编写正确的代码来打印每个数据。谢谢

你在数组中得到响应，替换这个：

foreach ($city as $c) { 
    echo $c->regionName;
}

到：

foreach ($city as $c) { 
    echo "Region :".$c['regionName'];
    echo "Country code : ".$c['countryName']."'n"; 
    echo "Cityname : ".$c['cityName']."'n";
}

您的$city变量包含 json 响应。解码它。

$city = json_decode($city, true);

您现在有一个要循环的数组。
