Laravel sort collection by date
To sort a Laravel collection by date, you can use the sortBy or sortByDesc method. Here’s an example of how to sort a collection of Post models by their created_at date in ascending order:
$posts = Post::all()->sortBy('created_at');
In this example, we are calling the all method on the Post model to retrieve all the posts from the database. Then, we are calling the sortBy method on the resulting collection and passing in the name of the created_at field as the sorting criteria. This will sort the collection in ascending order based on the created_at date.
If you want to sort the collection in descending order, you can use the sortByDesc method instead:
$posts = Post::all()->sortByDesc('created_at');
This will sort the collection in descending order based on the created_at date.
Note that if you have a collection of dates stored as strings, you may need to convert them to date objects using the strtotime function before sorting them. Here’s an example:
$dates = collect(['2022-01-01', '2021-01-01', '2023-01-01']);
$sortedDates = $dates->map(function ($date) {
return strtotime($date);
})->sortBy('created_at')->map(function ($date) {
return date('Y-m-d', $date);
});
In this example, we are first creating a collection of dates as strings. Then, we are using the map method to convert each date string to a Unix timestamp using the strtotime function.
Next, we are using the sortBy method to sort the dates by their Unix timestamps. Finally, we are using the map method again to convert the sorted Unix timestamps back to date strings.
