Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
Looks fine to me. https://3v4l.org/6iVoU
Are you sure this is related to opcache? What if you turn off optimizations?

these "structures" are a total mess
why don't you just use print_r() so that it becomes readable?
php > print_r($x);
Array
(
[1] => Array
(
[1] => x
[2] => y
[3] => Array
(
[0] => a
[1] => b
)
)
[2] => Array
(
[0] => x
)
)

Description:
------------
When I use unset to dele a specific array inside an array, it deletes the specific array and all
array on the same level behind this specific array.
My structure:
*0: 0: id -> 0
1: name -> Teig
2: doing ->
*3: 0: q -> 100
1: u -> g
2: p -> wheat_flour
*4: 1: q -> 100
1: u -> g
2: p -> sugar
*5: 2: q -> 100
1: u -> g
2: p -> milk
1: count -> 1
2: uidR -> 2
The star infront of the key says that it is an array.
If I execute
unset($array[0][1]);
the array *4 will be deleted but also the next one (*5). If after *5 additional arrays would be
follow, these would be also deleted.
I know, that in the past this was working, but I am sorry, I don't know when.
Test script:
---------------
<?php
$array [0]= ['id' => 0, 'name' => 'Teig', 'doing'
=> 'Test'];
$array[0][0] = ['q' => '100', 'u' => 'g',
'p' => 'wheat_flour'];
$array[0][1] = ['q' => '100', 'u' => 'g',
'p' => 'sugar'];
$array[0][2] = ['q' => '100', 'u' => 'g',
'p' => 'milk'];
$array[] = ['count' => '1', 'uidR' => '2'];
unset($array[0][1]);
Expected result:
----------------
*0: 0: id -> 0
1: name -> Teig
2: doing ->
*3: 0: q -> 100
1: u -> g
2: p -> wheat_flour
*5: 2: q -> 100
1: u -> g
2: p -> milk
1: count -> 1
2: uidR -> 2
Actual result:
--------------
*0: 0: id -> 0
1: name -> Teig
2: doing ->
*3: 0: q -> 100
1: u -> g
2: p -> wheat_flour
1: count -> 1
2: uidR -> 2
