To convert MySQL queries to Laravel's query builder, you can follow these steps:

1. Replace the raw MySQL queries with Laravel query builder methods.
2. Use the 'DB' facade to access the query builder instance.
3. Use the fluent query builder methods provided by Laravel such as select(), where(), orderBy(), join(), groupBy(), limit(), etc.
4. Refactor the MySQL queries to use Laravel's Eloquent ORM if possible for a more object-oriented approach.
5. Convert any MySQL specific syntax or functions to Laravel's equivalent methods.

Here's an example of converting a raw MySQL query to Laravel query builder:

MySQL query:

1

SELECT * FROM users WHERE id = 1;

Laravel query builder:

1
2
3

$user = DB::table('users')
            ->where('id', 1)
            ->first();

By following these steps, you can easily convert your MySQL queries to Laravel query builder, making your code more readable, maintainable, and secure.
