In Laravel, you can pass data to a SQL query using the query builder. Here's an example of how you can pass data to a query:

1
2
3
4
5
$age = 30; // Example data to pass to query

$results = DB::table('users')
            ->where('age', $age)
            ->get();


In this example, we are querying the users table and passing the $age variable as a parameter to the where clause in the query. You can pass data to the query in a similar way by using variables or values that you want to filter the results with.


You can also use parameter binding to pass data to a query, like this:

1
2
3
$age = 30; // Example data to pass to query

$results = DB::select('SELECT * FROM users WHERE age = ?', [$age]);


In this example, we are using parameter binding to pass the $age variable to the SQL query. The ? in the query string is a placeholder for the parameter value, and the second argument to the select method is an array of values that will be bound to the placeholders in the query.


Using parameter binding is a good practice as it helps protect against SQL injection attacks and also makes your code more maintainable.
