How to extract a value from this JSON response - php

Question

I am using the file_get_contents() function in PHP to retrieve the contents on a page containing a JSON response. However, I am struggling to get the "text" data.
$response = file_get_contents(someData)
I can use var_dump(json_decode($response)); to show the data, however, I am trying to get the data from the "text" field only within duration.
So far I have tried
$response[0];
$response->rows[0]->elements[0]->duration[0]->text;
But I cannot seem to get the data. I have pasted the response below
{
"destination_addresses" : [ "Manchester, UK", "Liverpool, Merseyside, UK" ],
"origin_addresses" : [ "London, UK" ],
"rows" : [
{
"elements" : [
{
"distance" : {
"text" : "335 km",
"value" : 335444
},
"duration" : {
"text" : "3 hours 36 mins",
"value" : 12955
},
"status" : "OK"
},
{
"distance" : {
"text" : "354 km",
"value" : 354415
},
"duration" : {
"text" : "3 hours 43 mins",
"value" : 13387
},
"status" : "OK"
}
]
}
],
"status" : "OK"
}

Answer 1

$response = json_decode(file_get_contents(someData));
$text = $response->rows[0]->elements[0]->duration->text;
var_dump($text);
Your only mistake was a [0] after duration.
