I've spent hours trying to find the answer to this question, but I'm struggling. I'm reasonably familiar with PHP and the various in-built functions, and can build a complex foreach() loop to do this, but I thought I'd ask to see if anyone has a smarter solution to my problem. I have an array in this form, Now I want to convert this into multidimensional based on list_id matched on next instance.I tried this solution but not worked well https://stackoverflow.com/a/65042103/4626270. This may be duplicate but not got output here
<pre>Array
(
[0] => Array
(
[list_id] => 5
[order_list_name] => meri list 3
[0] => Array
(
[list_id] => 5
[product_id] => 1
[product_name] => DUCHESS WHITE WINE 200 ml
[sku] => SKU0001
[qty] => 2
)
)
[1] => Array
(
[list_id] => 5
[order_list_name] => meri list 3
[0] => Array
(
[list_id] => 5
[product_id] => 2
[product_name] => CONNEXION DOUBLE ROCK 350 ml, Pack of 2
[sku] => SKU0002
[qty] => 8
)
)
[2] => Array
(
[list_id] => 7
[order_list_name] => meri list 9
[0] => Array
(
[list_id] => 7
[product_id] => 2
[product_name] => CONNEXION DOUBLE ROCK 350 ml, Pack of 2
[sku] => SKU0002
[qty] => 2
)
)
)
I am expecting output like this
<pre>Array
(
[0] => Array
(
[list_id] => 5
[order_list_name] => meri list 3
[0] => Array
(
[list_id] => 5
[product_id] => 1
[product_name] => DUCHESS WHITE WINE 200 ml
[sku] => SKU0001
[qty] => 2
),
[1] => Array
(
[list_id] => 5
[product_id] => 1
[product_name] => DUCHESS WHITE WINE 200 ml
[sku] => SKU0001
[qty] => 2
)
)
[1] => Array
(
[list_id] => 7
[order_list_name] => meri list 9
[0] => Array
(
[list_id] => 7
[product_id] => 2
[product_name] => CONNEXION DOUBLE ROCK 350 ml, Pack of 2
[sku] => SKU0002
[qty] => 2
)
)
)
