Laravel - Collections. How to separate array into 2 groups - php

Question

I have created 2 collections(arrays) which each contain an array of 5 items/events.
$events = App\get_event_data( $args )
$collection = collect($events['events']);
$event_chunks = $collection->chunk(5);
$event_chunks->toArray();
#foreach ($event_chunks as $chunk)
Output of the above:
object(Illuminate\Support\Collection)[27632]
protected 'items' =>
array (size=2)
0 =>
object(Illuminate\Support\Collection)[27630]
protected 'items' =>
array (size=5)
...
1 =>
object(Illuminate\Support\Collection)[27631]
protected 'items' =>
array (size=5)
...
In my next loop, it simply goes through every item of the array 1 by 1.
I need to split the 5 items into a further 2 groups:
group of 2
group of 3
so I can wrap a div around each group.
Current loop:
#foreach ($chunk as $key => $event)
<div class="item">
{{ $event['title'] }}
</div>
#endforeach
What I need:
<div class="item-group">
[item1, item2]
</div>
<div class="item-group">
[item3, item4, item5]
</div>
Full code:
{{-- Get all events --}}
#if( $events = App\get_event_data( $args ) )
#php
$collection = collect($events['events']);
$event_chunks = $collection->chunk(5);
$event_chunks->toArray();
#endphp
#foreach ($event_chunks as $chunk)
<div class="{{ $block }}__flex-grid">
#foreach ($chunk as $key => $event)
<div class="item">
{{ $event['title'] }}
</div>
#endforeach
</div>
#endforeach
#endif

Assuming that you will allways have 5 items, a solution could be:
<div class="item-group">
#foreach (array_slice($chunk->toArray(),0,2) as $key => $event)
<div class="item">
{{ $event['title'] }}
</div>
#endforeach
</div>
<div class="item-group">
#foreach (array_slice($chunk->toArray(),2) as $key => $event)
<div class="item">
{{ $event['title'] }}
</div>
#endforeach
</div>
Or if want to avoid code duplication:
#php $chunk = [array_slice($chunk->toArray(),0,2), array_slice($chunk,2)];
#foreach ($chunk as $group)
<div class="item-group">
#foreach ($group as $key => $event)
<div class="item">
{{ $event['title'] }}
</div>
#endforeach
</div>
#endforeach
If you don't know or not sure that you have 5, you may need to change the logic of the chunks/slice.

It's maybe too late to answer, but I've made a function to split arrays into as groups as you like.
function SplitInto($array, $groups = 2)
{
$members = count($array) / $groups;
if (count($array) % $groups) $members = (int)(count($array) / $groups) + 1;
return array_chunk($array, $members);
}
