I have a JSON string and i want to get the value.
$s='{
"subscriptionId" : "51c04a21d714fb3b37d7d5a7",
"originator" : "localhost",
"contextResponses" : [
{
"contextElement" : {
"attributes" : [
{
"name" : "temperature",
"type" : "centigrade",
"value" : "26.5"
}
],
"type" : "Room",
"isPattern" : "false",
"id" : "Room1"
},
"statusCode" : {
"code" : "200",
"reasonPhrase" : "OK"
}
}
]
}';
Here is the code which I used but it didn't work.
$result = json_decode($s,TRUE); //decode json string
$b=$result ['contextResponses']['contextElement']['value']; //get the value????
echo $b;
