I am having a strange issue with Undefined index in my PHP code.
foreach ($arr as $event) {
        $place = "";
        $place = "Location: ".$event['locations']['title'];
}
And I am getting that error: Undefined index: locations in...
['locations']['title'] is coming from the JSON I am parsing.
I know that there are some reserved words like $this, etc. But don't think locations is one of these words.
I have tried also declaring the locations like this
$locations = "";
But still see the error in the logs.
JSON
  [ {  
      "title":"8 Grand Pianos Concert (16 November 2019)",
      "timeFrom":"2019-11-16 19:00:00",
      "timeTo":"2019-11-16 22:00:00",
      "listText":"Concerts in.....",
      "url":"https://concert-16-november-2019",
      "imageUrl":"https://8108273152422838272_o.jpg?f=62051",
         "locations":{  
         "title":"Complex",
         "url":"https://locations/complex"
      }
   }
