输出国家代码到控制台

Hi I am trying to output country code to console or pass through javascript so I can do some conditional formatting. heres my code:

<?php
  $ip = $_SERVER['REMOTE_ADDR'];
  $details = json_decode(file_get_contents("http://ipinfo.io/{$ip}"));
  echo("<script>console.log('PHP: ".json_encode($details->country)."');
  </script>");
?>

My output in the console is PHP: null

UPDATE

To explain my objective: I have a wp site which is being blocked in China. I have several services which I believe is issue including:

• Google Analytics
• Google recaptcha
• Google Maps
• Google Fonts
• Vimeo

I am wanting to detect country code then if its china then do not display scripts/css in php server side.

Thanks,

You need to remove the curly brackets from the URL.

$details = json_decode(file_get_contents("http://ipinfo.io/$ip"));

How about a jQuery version of what you are trying to do. It is a lot easier than the PHP version in my opinion.

$.getJSON("https://ipinfo.io/",
    function(data){
      
       // show all options from data object
       //console.log(data);
       
       var country = data.country;
       var city = data.city;
       var loc = data.loc;
       var ip = data.ip
       
       var details = "<h1>"+ip+"</h1>"+"<br>COUNTRY: "+country+"<br>CITY: "+city+"<br>LOC: "+loc;
       
       $("#details").html(details);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


<div id="details"></div>

</div>

There is no problem with your code so far. (You can check with a hard-coded IP address ex. 8.8.8.8)

You are testing your code under localhost, so $_SERVER['REMOTE_ADDR'] returns the local IP Address instead of the public IP.

The site ipinfo.io will not work with local IP Addresses, so it will response something like {"ip":"192.xxx.xx.x","bogon":true}. So there is no property named country in the response, which means null.

If you deploy your code to a "real" server (which has a public IP address) then it will work.

Use ipinfo.io's official PHP client library: https://github.com/DavidePastore/ipinfo

<?php   
    // Initialize ipinfo 
    $ipInfo = new DavidePastore\Ipinfo\Ipinfo(array(
        "token" => "your_api_key" 
    ));

    $ip = $_SERVER['REMOTE_ADDR'];

    //Get all the properties
    $host = $ipInfo->getFullIpDetails($ip);

    // Output Country to JavaScript Console
    echo("<script>console.log('PHP: ".$host->getCountry()."');</script>");
?>
