PHPの国名は表示されません

Question

私が書いたコードに問題があります。私はコードを何回かテストしたが、うまくいきましたが、問題は、ある特定のサーバー（Namecheap）でこのPHPファイルを実行すると、正しく動作しない関数がいくつかあり、別のサーバー（1and1）それは100％良くなります。私は自分の市場を確立するためにIPに基づいて国名を取得したいと思いますが、それを行うコードがありますが、Namecheapでは$ country_nameは表示されませんが、1and1ではcertenlyします。これはPHPのバージョンと関係があるのだろうか？皆さんのおかげで、いくつかのドキュメントを参照して、自分で解決することができるかどうかを確認できます。

私は十分にはっきりしていることを願っています。 ありがとうございます。あなたがいないfile_get_content魔女が本当にWebページの結果を取得していないカールの機能を使用する必要がありますipinfoドキュメントよると

Answer 1

：サーバ上のファイルの

リンクはNamecheapここで

1and1は私のPHPコードであるここにありますjsonデータ。ここで

curl ipinfo.io/8.8.8.8 
{ 
    "ip": "8.8.8.8", 
    "hostname": "google-public-dns-a.google.com", 
    "loc": "37.385999999999996,-122.0838", 
    "org": "AS15169 Google Inc.", 
    "city": "Mountain View", 
    "region": "California", 
    "country": "US", 
    "phone": 650 
}

PHPのカールを持つ例：私は、これはあなたを助けることを願って

<?php 
$ch = curl_init(); 

curl_setopt($ch, CURLOPT_URL, "http://ipinfo.io/8.8.8.8"); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER , true); 

$result=curl_exec($ch); 

//print_r($result); 

$jsonResult = json_decode($result); 

echo "Country: ".$jsonResult->country; 

curl_close($ch); 
?> 

。

Answer 2

APIリンクが無効です。使用方法：別のIPの詳細については、独自のIP

http://ipinfo.io/8.8.8.8/jsonため

http://ipinfo.io/json。

あなたが唯一の国での使用についての情報を取得したい場合：

http://ipinfo.io/8.8.8.8/country（JSONのない、プレーンテキストのみ）

あなたのコード：

$ip = getenv("REMOTE_ADDR"); //or something else ip 
$country_code = file_get_contents("http://ipinfo.io/$ip/country"); //plain country code, no json 

（...）

// Holds country name value after checking array. 
$country_name = $countries[$country_code]; 

もちろん8.8.8.8正しいアドレスに変更
