How to get JSON response in to PHP variables - php

Question

I am getting following response in JSON format and I want it to convert it into PHP variables.
JSON:
{"CreateTransactionResponse":{"CreateTransactionResult":{"TransportKey":"aa900d54-7bfb-47e9-a5de-e423ec34a900"
,"ValidationKey":"fbb28b32-f439-4801-a434-99c70aa388ca","Messages":{}}}}
output should be PHP:
$transkey = aa900d54-7bfb-47e9-a5de-e423ec34a900;
$vkey = fbb28b32-f439-4801-a434-99c70aa388ca
please advice me how to do it.

Answer 1

Just simply use json_decode();
$result= json_decode($jSon);
var_dump($result); // to see the output

Answer 2

json to array(json_decode) and then extract from array.
$arr = json_decode($json, true);
extract($arr);
var_dump($CreateTransactionResponse);
Output:
array (size=1)
'CreateTransactionResult' =>
array (size=3)
'TransportKey' => string 'aa900d54-7bfb-47e9-a5de-e423ec34a900' (length=36)
'ValidationKey' => string 'fbb28b32-f439-4801-a434-99c70aa388ca' (length=36)
'Messages' =>
array (size=0)
empty
More about extract
use $CreateTransactionResult['TransportKey'] to access Transport Key from JSON. Similarly $CreateTransactionResult['ValidationKey'] for Validation Key.

Answer 3

If you want to access your json try to decode it first:
$result = json_decode($yourJSON, true);
foreach($result['CreateTransactionResponse'] as $key => $val){
echo $transkey = 'TransportKey= ' . $val['TransportKey'] . '<br/>;
echo $vkey = 'ValidationKey= ' . $val['ValidationKey'];
}
Or if it is an array of JSON's
$result = json_decode($yourJSON, true);
$data = [];
foreach($result['CreateTransactionResponse'] as $key => $val){
$data[] = [
'TransportKey' => $val['TransportKey'],
'ValidationKey' => $val['ValidationKey']
];
}
print_r($data);

Answer 4

try this code it will work
$JSON='{"CreateTransactionResponse":{"CreateTransactionResult":{"TransportKey":"aa900d54-7bfb-47e9-a5de-e423ec34a900" ,"ValidationKey":"fbb28b32-f439-4801-a434-99c70aa388ca","Messages":{}}}}';
$arr=json_decode($JSON, TRUE);
foreach ($arr as $value) {
foreach ($arr['CreateTransactionResponse'] as $key => $var) {
echo 'TransportKey = '.$var['TransportKey'].'<br>';
echo 'ValidationKey = '.$var['ValidationKey'].'<br>';
foreach ($var['Messages'] as $key => $msg) {
echo 'Messages = '.$msg.'<br>';
}
}
}

Answer 5

In this case,If its a single and TransportKey and a single ValidationKey value (not an array/object is passed) at a time, this is the simplest. Else if object contains objects or inside objects that we want to use or convert to variable, should use a foreach to loop through the object.
//Debuggig
//The string you provided is converted to a json object
//In your case if it is a json object already pass directly it to $j
//below is just for debugging and understanding
//$json='{"CreateTransactionResponse":{"CreateTransactionResult":{"TransportKey":"aa900d54-7bfb-47e9-a5de-e423ec34a900","ValidationKey":"fbb28b32-f439-4801-a434-99c70aa388ca","Messages":{}}}}';
//$j=json_decode($json);
$transkey=$j->CreateTransactionResponse->CreateTransactionResult->TransportKey;
$vkey=$j->CreateTransactionResponse->CreateTransactionResult->ValidationKey;
echo $transkey."</br>";
echo $vkey."<br/>";
/*result as said:
aa900d54-7bfb-47e9-a5de-e423ec34a900
fbb28b32-f439-4801-a434-99c70aa388ca
