In this Laravel tutorial in hindi, we will learn about the functionality called List Order in Laravel.
A list is a data type that can hold an ordered sequence of values. In Laravel, lists are stored as arrays and can be accessed using a bracket notation. Lists are one of the most common data structures in programming languages. They are used to store data in an ordered sequence. Lists are one of the most important data types in many programming languages because they allow for efficient insertion and deletion from the middle of the sequence without disturbing other elements in the list.
You must use the orderBy() in Laravel and supply the table column you wish to utilise as the ordering criteria in the database query in order to sort the results. This will allow you more freedom to create a query that will just retrieve the database results you require.
The orderBy() function in Laravel is used to sort the database results. It has two uses:
- Using a specific column to order the results.
- To sort the results by a column and then by another column (ascending or descending).
The syntax of orderBy() is:
$data = DB::table('users')->orderBy('id');
It sorts the table by id.
The list order functionality in Laravel allows you to sort any kind of data, including arrays and objects, by ascending or descending order. This can be done by specifying the name of the field from which you want to sort your data. The syntax for this is as follows:
$users = User::orderBy('last_name'); //sort by last name
$users = User::orderBy('-last_name'); //sort by last name descending
