How to use update() functionality in laravel?

@hal.littel 

The update() method in Laravel is used to update records in the database based on certain criteria. Here's how you can use it:

1. Define a model: Make sure you have a model defined for the table you want to update. For example, if you have a "User" model for a "users" table, you can use the update method on the User model.
2. Build the query: You can use the where() method to specify the criteria for updating the record. For example, if you want to update a user record with a specific ID, you can use the following code:

1
2

User::where('id', $userId)->update([
    'name' => 'John Doe',
    'email' => 'john.doe@example.com'
]);

1. Execute the query: Finally, call the update() method on the model instance to update the records in the database.

$user = User::find($userId);

$user->update([
    'name' => 'John Doe',
    'email' => 'john.doe@example.com'
]);

This will update the "name" and "email" fields of the user with the specified ID in the database.

Remember to handle validation and error checking appropriately when using the update() method to prevent any unauthorized updates or errors.
