How can I get a specific value in this PHP array? - php

Question

I'm setting up a Cloudinary listing of uploaded videos and I want to get the metadata of that video.
I have a print_r($result):
<pre>
Cloudinary\Api\Response Object
(
[rate_limit_reset_at] => 123123123
[rate_limit_allowed] => 123
[rate_limit_remaining] => 123
[storage:ArrayObject:private] => Array
(
[public_id] => dog
[format] => mp4
[version] => 123123123
[resource_type] => video
[type] => upload
[created_at] => 2019-07-29T07:32:50Z
[bytes] => 123123
[width] => 321
[height] => 456
[backup] => 1
[access_mode] => public
[url] => http://res.cloudinary.com/demo/video/upload/dog.mp4
[secure_url] => https://res.cloudinary.com/demo/video/upload/dog.mp4
[next_cursor] => 123123123
[derived] => Array
(
[0] => Array
(
[transformation] => /jpg
[format] => jpg
[bytes] => 86438
[id] => 123123123
[url] => http://res.cloudinary.com//demo/video/upload/dog.jpg
[secure_url] => https://res.cloudinary.com/demo/video/upload/dog.mp4
[extension] => jpg
)
[1] => Array
(
[transformation] => t_media_lib_thumb/jpg
[format] => jpg
[bytes] => 3293
[id] => 12123123
[url] => https://res.cloudinary.com/demo/video/upload/dog.jpg
[secure_url] => https://res.cloudinary.com/demo/video/upload/dog.jpg
[extension] => jpg
)
)
)
)
</pre>
I tried getting the value using this format but it says undefined index. echo $result[4]['width'] or echo $result['storage:ArrayObject:private']['width'];

Answer 1

I talked to a cloudinary support ad he said that "you should be able to access the data returned within [storage:ArrayObject:private] by simply ignoring it and requesting the index that you desire directly from $result. Meaning you can use or and so on with the other paramters."
So basically, just removing the index solved my problem like so:
<?php echo $result['height']; ?> <?php echo $result['width']; ?>

Have a look at this https://github.com/cloudinary/cloudinary_php/blob/master/src/Api/Response.php in order to better understand the object you are getting back.
Afterwards, look at the ArrayObject documentation here https://www.php.net/manual/en/class.arrayobject.php, as your Response object extends this class. Using getArrayCopy() to transform your object into an array should be what you need.
Bear in mind that I am not familiar with the API and that there may be better options to get what you need.
