laravel delete multiple hops

Laravel is a very popular PHP framework that provides a series of powerful features to help developers build applications more efficiently. In Laravel, deleting a record is very simple. But what if we need to delete multiple records? This article will introduce how to delete multiple records in Laravel.

In Laravel, Eloquent provides many methods to delete records. Among them, the most commonly used method is probably the delete method. For example:

$user = User::find(1);
$user->delete();

The above code will delete the user record with id being 1. But what if we need to delete multiple records? At this time we can use the whereIn method. For example:

$ids = [1, 2, 3];
User::whereIn('id', $ids)->delete();

The above code will delete three records with id being 1, 2, and 3.

However, the whereIn method only applies to deleting specified records. What if we need to delete records based on conditions? At this time we can use the where method. For example:

User::where('age', '>', 18)->delete();

The above code will delete all user records older than 18 years old.

In addition to the above methods, Laravel also provides some other methods to delete multiple records:

• delete(): Delete all records.
• truncate(): Clear all records in the table.

However, these two methods are irreversible, and the data cannot be recovered after execution. So be careful when using it.

In addition, Laravel also provides a very useful method forceDelete(). This method can permanently delete records, even if SoftDeletes is used. For example:

$users = User::onlyTrashed()->where('deleted_at', '<', now()->subMonths(6))->get();
$users->forceDelete();

The above code will delete user records that have been soft deleted for 6 months.

To summarize, there are several methods to delete multiple records in Laravel:

• delete(): Delete the specified record.
• whereIn(): Delete a specified set of records.
• where(): Delete records according to conditions.
• truncate(): Clear all records in the table.
• forceDelete(): Permanently delete the record.

It should be noted that you must be cautious when deleting multiple records and confirm that they are correct before performing the deletion operation.
