Eloquent updates multiple records in batches (update if they exist, insert if they do not exist)

It is not a batch assignment of multiple fields in one record.

Similar to batch insert:

<code>DB::table('users')->insert(array(
  array('email' => 'aaa@example.com', 'name' => 'zhangsan', 'age'=> 0),
  array('email' => 'bbb@example.com', 'name' => 'wangwu', 'age'=> 0),
  ...
));
</code>

Is there any similar sentence:

<code>DB::table('users')->update( array(
  array('email' => 'aaa@example.com', 'name' => 'zhangsan', 'age'=> 20),
  array('email' => 'bbb@example.com', 'name' => 'wangwu', 'age'=> 25),
  array('email' => 'ccc@example.com', 'name' => 'chenliu', 'age'=> 50),
  ...
) , 'email' );
</code>

The functions implemented are:

1. When the query conditions exist, update the original data in batches;

<code>例：
email='aaa@example.com'时， 'age'修改为 20,
email='bbb@example.com'时， 'age'修改为 25,
...
</code>

2. When the query conditions do not exist, insert data in batches.

<code>例：
email='ccc@example.com'时， 'age'修改为 50,
...
</code>

Copy after login

My code is:

<code>public function updateOrCreate (Request $request) {
  
  $insert_array = [];

  $datas = $request->all();

  foreach ($datas as $key=> $data) {
    $user = User::where('email', $data['email'])->first();
    if (!$user) {
        $insert_array[] = $data;
    // 更新原数据
    } else {
        $user->email = $data['email'];
        $user->age = $data['age'];
        $user->save();
    }
  }
  // 批量插入数据
  User::insert($insert_array);
}
</code>

Copy after login

The above code will cause performance problems when the number of updated data is more than a thousand!

Please advise, is there a better solution?

Please give me more advice.

1. Change the query to a DB operation
2. Do not have a query operation in foreach
3. You can assemble all emails into one query statement, and the server will compare which record currently exists
