Accessing Json value of variable with a colon (:) in between using Php

Question

I need to access the value of a variable element in Json, the problem however the variable has a colon (:) and i keep getting undefined variable every time.

{#370 ▼
  +"im:name": {#371 ▶}
  +"im:image": array:3 [▶]
  +"im:itemCount": {#380 ▶}
  +"im:price": {#381 ▶}
  +"im:contentType": {#385 ▶}
  +"rights": {#387 ▶}
  +"title": {#388 ▶}
  +"link": {#390 ▶}
  +"id": {#391 ▶}
  +"im:artist": {#393 ▶}
  +"category": {#396 ▶}
  +"im:releaseDate": {#397 ▶}
}

for example $feed->category is okay , but anything with : in between like $feed->im:category throws an error.

Could be worth reading https://stackoverflow.com/questions/4887300/using-simplexml-to-read-rss-feed,although https://stackoverflow.com/questions/250679/best-way-to-parse-rss-atom-feeds-with-php and a few others may also help. — Nigel Ren, Aug 12 '19 at 05:20
simplexml_load_string in some cases does not capture all the details neede — TechPotter, Aug 12 '19 at 06:04
I would be surrised that it misses anything and converting it to JSON can cause all sorts of problems. — Nigel Ren, Aug 12 '19 at 06:12
I didn't convert it to json, it was optional to use either xml or json, it is simpler for me to work with json than xml except for the case with colon. — TechPotter, Aug 12 '19 at 09:40

Use curly brace syntax

$feed->{'im:category'}

Try to json_decode it and force the use of associative arrays with JSON_OBJECT_AS_ARRAY.
