json api account search in php

Question

I have small problem with my project. I don't know much, because I'm only learning now PHP arrays, I want to create some like this

PewDiePie
PewDiePie1
PewDiePie2

and on click href to account_id.

Here is PHP code:

$link = $_GET['search'];
$str_data = file_get_contents("https://api.worldoftanks.eu/wot/account/list/?application_id=ID_OF_APPLICATION&search=$link");
$data = json_decode($str_data,true);

function echo_array($a, $key){
    foreach($a as $key1 => $array1){
        if(!is_array($array1)){
            echo "$key $key1 : $array1 </br>";
        }else{
            echo_array($array1,"$key $key1");
        }
    }
}
echo_array($data,'');

This is output of PHP file

status: ok
meta count: 100
data 0 nickname: Pewdiepie
data 0 account_id: 501337127
data 1 nickname: Pewdiepie00
data 1 account_id: 510468398
data 2 nickname: pewdiepie007
data 2 account_id:511343434

but I want to make only some like $nickname and $account_id , but when I tried, it was been a fail. Will you advise me?

Answer 1

Your function need to be:

function echo_array($a, $key){
    foreach($a['data'] as $data){
            echo $data['nickname'];
            echo $data['account_id'];
    }
}

If you post the Json result, i can more explain how acces to the children node

Answer 2

Okey i have solution, because in code is 2 same arrays

$link = $_GET['search'];
$str_data = file_get_contents("https://api.worldoftanks.eu/wot/account/list/?application_id=#&search=$link");
//there is data $data = json_decode($str_data,true);

function echo_array($a, $key){
    foreach($a['data'] as $data1){
          //and there is data  echo $data['nickname'];
            echo $data['account_id'];
    }
}
echo_array($data,'');

i changed to

$link = $_GET['search'];
$str_data = file_get_contents("https://api.worldoftanks.eu/wot/account/list/?application_id=#&search=$link");
$data = json_decode($str_data,true);

function echo_array($a, $key){
    foreach($a['data'] as $data1){
            echo $data1['nickname'];
            echo $data1['account_id'];
    }
}
echo_array($data,'');

and now is working, Thank you Jonathan, have a nice day:)
