Many ways of deleting records in Laravel 4.1
1) When you want to delete records from your database, simply call the delete method:
$affected = DB::table('users')->where('id', '=', 1)->delete();
2) Want to quickly delete a record by its ID? No problem. Just pass the ID into the delete method:
$affected = DB::table('users')->delete(1);
3) If you want to delete multiple records by id at once, passing their ids in an array - use the following
$users_to_delete = array(1, 2, 3);
DB::table('users')->whereIn('id', $users_to_delete)->delete();
4) If you want to delete multiple records by id at once, passing an array of users - use the following
//(case A) User fields indexed by number 0,1,2..
$users_to_delete = array(
'0'=> array('1','Frank','Smith','Whatever'),
'1'=> array('5','John','Johnson','Whateverelse'),
);
$ids_to_delete = array_map(function($item){ return $item[0]; }, $users_to_delete);
DB::table('users')->whereIn('id', $ids_to_delete)->delete();
//(case B) User fields indexed by key
$users_to_delete = array(
'0'=> array('id'=>'1','name'=>'Frank','surname'=>'Smith','title'=>'Whatever'),
'1'=> array('id'=>'5','name'=>'John','surname'=>'Johnson','title'=>'Whateverelse'),
);
$ids_to_delete = array_map(function($item){ return $item['id']; }, $users_to_delete);
DB::table('users')->whereIn('id', $ids_to_delete)->delete();
5) Deleting An Existing Model By Key
User::destroy(1);
User::destroy(array(1, 2, 3));
User::destroy(1, 2, 3);
6) Of course, you may also run a delete query on a set of models:
$affectedRows = User::where('votes', '>', 100)->delete();
