json decode in php

Question

I have the following json string and I want to retrieve just the email address from it. How do I do it in php?

{\"communications\":{\"communication\":[{\"@a         


        

Answer 1

Another twist on how inerte did it would be to access it like:

$json_object = '{"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",

                            {"@array":"true","@id":"11111","@uri":"xyz/v1/Communications/111111111","household":

                            "person": {"@id":"2222222","@uri":"xyz/v1/People/22222222"},
                            "communicationType": {"@id":"2","@uri":"xyz/v1/Communications/CommunicationTypes/2","name":"Work Phone"},

                            "person":{"@id":"244404","@uri":"xyz/v1/People/1111"},
                            "communicationType":{"@id":"3","@uri":"xyz/v1/Communications/CommunicationTypes/3","name":"Mobile"},

                            "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"}
                         ]
                       }
                      }';


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