Get the value of key in array?

Question

I have an array returned to woocommerce from payment gateway as order comment. I need to access it to get a value.

The array is this:

    Array

[0] => WP_Comment Object

Edit my answer. Your comment_content is a string not an array. So you don't have to access it at all you have another nested array below that.

$array[0][0]['txId'];

Also your approaches are used for objects and not for arrays.

This won't work because `comment_content` is a string, not an array – Nick Jan 25 '19 at 08:19
You are right i edit my answer. there are 2 nested fields in there. i constructed the array locally to see the right structure of it. I got bugged on how can an array field have a string and an array value nest at the same time. Thanks for pointing. – pr1nc3 Jan 25 '19 at 08:27
"how can an array field have a string and an array value nest at the same time"? it can't. the entire field is a string. that's why the output of `print_r` displays the way it does in the question. – Nick Jan 25 '19 at 08:31
Yes i already edited my answer. I got stuck there thinking for a while :) – pr1nc3 Jan 25 '19 at 08:32

Based on the output you have shown us, comment_content is a string, not a structure. You can extract the value of txId from it using preg_match e.g.

preg_match('/\[txId\] => ([a-f0-9-]+)/', $array[0]->comment_content, $matches);
echo $matches[1];

Output:

edf3354c-af38-49f7-810a-e79234e6604d

You should probably look into how that element is being created so that it can be a structure rather than a string, it will make your life a lot easier in future.

That will do. Thank you.Cant control the output by the way. – fikimk Jan 25 '19 at 08:31 — fikimk, Jan 25 '19 at 08:31
