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>
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>
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

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
