In Laravel, “limit” and “offset” are commonly used for database queries to retrieve a subset of results from a table.

• Limit: The “limit” clause specifies the maximum number of records to be returned in a query result. It restricts the result set to a specific number of rows. For example, if you set the limit to 10, the query will return a maximum of 10 records.
• Offset: The “offset” clause determines the starting point or position from where the result set should begin. It allows you to skip a specified number of rows before returning the remaining records. For example, if you set the offset to 20, the query will skip the first 20 rows and start returning records from the 21st row onwards.

Together, “limit” and “offset” are often used for pagination purposes, where you can retrieve a specific number of records per page by setting the limit, and navigate between pages by adjusting the offset accordingly.

Here’s an example of how you can use “limit” and “offset” in Laravel for database queries:

$limit = 10; // Number of records to retrieve per page
$page = 2; // Current page number

$offset = ($page - 1) * $limit; // Calculate the offset

$users = DB::table('users')
            ->orderBy('id')
            ->offset($offset)
            ->limit($limit)
            ->get();

foreach ($users as $user) {
    echo $user->name;
    // Other processing...
}

In this example, we are retrieving 10 records per page (specified by the $limit variable) starting from the second page (specified by the $page variable). The offset is calculated by subtracting 1 from the current page number and multiplying it by the limit.

The DB::table(‘users’) specifies the table we want to query, and orderBy(‘id’) ensures that the results are ordered by the id column (you can change it to any column you desire).

The offset($offset) and limit($limit) methods are used to apply the offset and limit to the query. Finally, get() executes the query and retrieves the records.
