I'm trying to concatenate a set collection to another set of collection. I see in Laravel 5.5 it has concat function, but for compatibility reason I have to use until Laravel 5.3 only.
I tried merge function but it is not concatenating but merging instead.
What are other workaround, or how can I update the Laravel Collection without update the whole Laravel package?
You can add functionality to Illuminate\Support\Collection via "macro"s if you want to:
\Illuminate\Support\Collection::macro('concat', function ($source) {
$result = new static($this);
foreach ($source as $item) {
$result->push($item);
}
return $result;
});
$new = $someCollection->concat($otherOne);
Copied the method from 5.5.
I have a short blog post about macros in Laravel in general, if it helps:
asklagbox blog - Laravel macros
Laravel 5.5 Docs - Collections - Extending Collections Though this is from 5.5 docs Collection has had this macro functionality for awhile now.
Okay nevermind, I'm using code below as workaround,
$first_collection->each(function($element) use (&$second_collection) {
$second_collection->push($element);
});
A merge function is just what you need.
The documenation says
If the given items's keys are numeric, the values will be appended to the end of the collection:
Which is just what you need.
If you are not sure about items keys, you can always use ->values() function
so the final design would be:
use Illuminate\Support\Collection;
...
$payments = new Collection();
$payments = $payments
->merge($payments1->values())
->merge($payments2->values());
