Editor to share with you how to use the filter () method in the Laravel collection, I believe most people do not know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's go to know it together.

Filter ()

Filter, one of the most useful laravel collection methods, allows you to filter collections using callbacks. It passes only those items that return true. All other items have been deleted. Filter returns a new instance without changing the original instance. It accepts value and key as two parameters in the callback.

$filter = $collection- > filter (function ($value, $key) {if ($value ['user_id'] = = 2) {return true;}}); $filter- > all ()

The all method returns the underlying array. The above code returns the following response.

[1 = > ["user_id" = > 2, "title" = > "Testing in Laravel", "content" = > "Testing File Uploads in Laravel", "category" = > "php"] these are all the contents of the article "how to use the filter () method in the Laravel collection".
