  • i think json structure is wrong i.e [{},{}], You need to end the json – M.Hemant Mar 18 '19 at 11:17
  • whats `json_last_error_msg()` say? Probably non-utf-8 `◀` `preg_replace('/[^[:print:]]/', '', $string)` – ArtisticPhoenix Mar 18 '19 at 11:18

It is returning null because it's not valid JSON. It's missing a } and a ] on the end.

Compare here:

<?php

var_dump(json_decode('[{"public_id":"pdf/Eagle_s_Crest_s1khaa","version":1552905253,"signature":"976a2475ba858beeb33d533b4bdd897c7730574c","width":3543,"height":5315,"format":"png","resource_type":"image","created_at":"2019-03-18T10:34:13Z","tags":[],"bytes":579592,"type":"upload","etag":"9c1ce7ee6f0d1a7ff540d9e06cfbc2bf","placeholder":false,"url":"http://res.cloudinary.com/dowh9bxad/image/upload/v1552905253/pdf/Eagle_s_Crest_s1khaa.png","secure_url":"https://res.cloudinary.com/dowh9bxad/image/upload/v1552905253/pdf/Eagle_s_Crest_s1khaa.png","access_mode":"public","existing":false,"original_filename":"Eagle ◀"'));

var_dump(json_decode('[{"public_id":"pdf/Eagle_s_Crest_s1khaa","version":1552905253,"signature":"976a2475ba858beeb33d533b4bdd897c7730574c","width":3543,"height":5315,"format":"png","resource_type":"image","created_at":"2019-03-18T10:34:13Z","tags":[],"bytes":579592,"type":"upload","etag":"9c1ce7ee6f0d1a7ff540d9e06cfbc2bf","placeholder":false,"url":"http://res.cloudinary.com/dowh9bxad/image/upload/v1552905253/pdf/Eagle_s_Crest_s1khaa.png","secure_url":"https://res.cloudinary.com/dowh9bxad/image/upload/v1552905253/pdf/Eagle_s_Crest_s1khaa.png","access_mode":"public","existing":false,"original_filename":"Eagle ◀"}]'));

Either you pasted here the wrong JSON, or the upload plugin is returning invalid JSON.

If you use json_decode , i suggest you look at the doc : http://php.net/manual/fr/function.json-decode.php Since we don't have your PHP code here i suppose that the second parameter "assoc" is not included in your code and may be the reason of your troubles
