json decode in php

Question

私は以下のjson文字列を持っています。私はそれから電子メールアドレスを取得したいと思います。どのように私はPHPでそれを行うのですか？

{"communications":{"communication":[{"@array":"true","@id":"23101384","@uri":"xyz/v1/Communications/1111","household":{"@id":"111111","@uri":"xyz/v1/Households/5465465"},"person":{"@id":"","@uri":""},"communicationType":{"@id":"1","@uri":"xyz/v1/Communications/CommunicationTypes/1","name":"Home Phone"},"communicationGeneralType":"Telephone","communicationValue":"1111","searchCommunicationValue":"2693240758","listed":"true","communicationComment":null,"createdDate":"2008-11-10T12:31:26","lastUpdatedDate":"2009-08-11T23:40:02"},{"@array":"true","@id":"11111","@uri":"xyz/v1/Communications/111111111","household":{"@id":"14436295","@uri":"xyz/v1/Households/11111"},"person":{"@id":"2222222","@uri":"xyz/v1/People/22222222"},"communicationType":{"@id":"2","@uri":"xyz/v1/Communications/CommunicationTypes/2","name":"Work Phone"},"communicationGeneralType":"Telephone","communicationValue":"11111","searchCommunicationValue":"789787987","listed":"false","communicationComment":null,"createdDate":"2009-08-09T15:49:27","lastUpdatedDate":"2009-08-11T23:40:02"},{"@array":"true","@id":"11111","@uri":"xyz/v1/Communications/11111","household":{"@id":"1111","@uri":"xyz/v1/Households/1111"},"person":{"@id":"244404","@uri":"xyz/v1/People/1111"},"communicationType":{"@id":"3","@uri":"xyz/v1/Communications/CommunicationTypes/3","name":"Mobile"},"communicationGeneralType":"Telephone","communicationValue":"22222","searchCommunicationValue":"5475454","listed":"true","communicationComment":null,"createdDate":"2008-11-10T12:31:26","lastUpdatedDate":"2009-08-11T23:40:02"},{"@array":"true","@id":"15454","@uri":"xyz/v1/Communications/111111","household":{"@id":"14436295","@uri":"xyz/v1/Households/1111"},"person":{"@id":"244444474","@uri":"xyz/v1/People/111111"},"communicationType":{"@id":"4","@uri":"xyz/v1/Communications/CommunicationTypes/4","name":"Email"},"communicationGeneralType":"Email","communicationValue":"email@needthis.com","searchCommunicationValue":"email@needthis.com","listed":"true","communicationComment":null,"createdDate":"2008-11-10T12:31:26","lastUpdatedDate":"2009-08-11T23:39:06"}]}} 

Answer 1

inerteはそれが好きでそれにアクセスすることですやった方法についてのもう一つのねじれ：私が

を書か

$json_object = '{"communications":

    $json_decoded = json_decode($json_object); 
    echo "email: ".$json_decoded->communications->communication[3]->communicationValue."<br />"; 

Answer 2

あなたはjson_decode Dあなたのデータこうして持って考える：あなたが使用することができます

$data = json_decode($json); 

をvar_dump（まあ、それは上があると便利ですXdebug拡張子、で使用される場合、出力は道良く見えるのですところで開発マシン、）あなたのデータに何があるか知っている：

// Allows you to know what's in the data ;-) 
var_dump($data);

あなたはこのような何かを探しているデータにアクセスすることができるはずです意味：：210あなたはこのような何かを得るでしょう

foreach ($data->communications->communication as $communication) { 
    if ($communication->communicationGeneralType == 'Email') { 
     var_dump($communication->communicationValue); 
     var_dump($communication->searchCommunicationValue); 
    } 
} 

あなたを取得しますどの：

string 'email@needthis.com' (length=18) 
string 'email@needthis.com' (length=18) 

「communications」は決定することができる「communication」を含むオブジェクト、オブジェクトの配列、communicationGeneralTypeを含む各一つであります現在の通信が電子メールかどうかを判断する。

場合は、communicationValueフィールドまたはsearchCommunicationValueフィールドを使用できます。このことができます

そして、私は本当にすべてのcommunicationの要素を反復処理せずにこれを行う方法を見ていない...

願っています！

Answer 3

json_decode()を使用できます。あなたの例の文字列は、そこに私が今考えするのは少し複雑ですが、私自身の例として：

$json = '{"a":"apples","b":["bananas","boysenberries"],"c":"carrots"}'; 

$arr = json_decode($json); 
echo $arr['a']; // "apples" 
echo $arr['b'][0]; // "bananas" 

Answer 4

<?php 
$string = '{"communications":{"communication":[{"@array":"true","@id":"23101384","@uri":"xyz/v1/Communications/1111","household":{"@id":"111111","@uri":"xyz/v1/Households/5465465"},"person":{"@id":"","@uri":""},"communicationType":{"@id":"1","@uri":"xyz/v1/Communications/CommunicationTypes/1","name":"Home Phone"},"communicationGeneralType":"Telephone","communicationValue":"1111","searchCommunicationValue":"2693240758","listed":"true","communicationComment":null,"createdDate":"2008-11-10T12:31:26","lastUpdatedDate":"2009-08-11T23:40:02"},{"@array":"true","@id":"11111","@uri":"xyz/v1/Communications/111111111","household":{"@id":"14436295","@uri":"xyz/v1/Households/11111"},"person":{"@id":"2222222","@uri":"xyz/v1/People/22222222"},"communicationType":{"@id":"2","@uri":"xyz/v1/Communications/CommunicationTypes/2","name":"Work Phone"},"communicationGeneralType":"Telephone","communicationValue":"11111","searchCommunicationValue":"789787987","listed":"false","communicationComment":null,"createdDate":"2009-08-09T15:49:27","lastUpdatedDate":"2009-08-11T23:40:02"},{"@array":"true","@id":"11111","@uri":"xyz/v1/Communications/11111","household":{"@id":"1111","@uri":"xyz/v1/Households/1111"},"person":{"@id":"244404","@uri":"xyz/v1/People/1111"},"communicationType":{"@id":"3","@uri":"xyz/v1/Communications/CommunicationTypes/3","name":"Mobile"},"communicationGeneralType":"Telephone","communicationValue":"22222","searchCommunicationValue":"5475454","listed":"true","communicationComment":null,"createdDate":"2008-11-10T12:31:26","lastUpdatedDate":"2009-08-11T23:40:02"},{"@array":"true","@id":"15454","@uri":"xyz/v1/Communications/111111","household":{"@id":"14436295","@uri":"xyz/v1/Households/1111"},"person":{"@id":"244444474","@uri":"xyz/v1/People/111111"},"communicationType":{"@id":"4","@uri":"xyz/v1/Communications/CommunicationTypes/4","name":"Email"},"communicationGeneralType":"Email","communicationValue":"email@needthis.com","searchCommunicationValue":"email@needthis.com","listed":"true","communicationComment":null,"createdDate":"2008-11-10T12:31:26","lastUpdatedDate":"2009-08-11T23:39:06"}]}}'; 

$encoded = json_decode($string, JSON_FORCE_OBJECT); 

echo $encoded['communications']['communication'][3]['communicationValue']; 

echo "\n"; 

echo $encoded['communications']['communication'][3]['searchCommunicationValue']; 

?> 

しかしcommunicationValueまたはsearchCommunicationValueあれば、これまでcommunicationのインデックス3から抜け出す、あなたは」トラブルに陥るおそらく、communicationをループし、これらの文字列をそのキー/値で検索する必要があります。

Answer 5

ニースの例では、構造ごとにすべての値が表示され、機能にjson_objectと1を渡します。

function decodejson($value,$num){ 
    if (count($value,0) > 0 && is_array($value)){ 
     foreach ($value as $key =>$tvalue){ 
      if (is_array($tvalue)){ 
       //echo $key."-<br />"; 
       $num++; 
       decodejson($tvalue,$num); 
      }else 
       echo str_repeat("&nbsp;", $num).$key."->".$tvalue."<br />"; 
     } 
    }else 
     echo str_repeat("&nbsp;", $num).$key."->".$value."<br />"; 
}
