For laravel paging, it comes with a paginate method, which is very useful, but it also has limitations.
So I wrote my own paging for this, the specific code is as follows
<?php namespace ...; use ...; /** * 自定义分页类,适合少数据的查询,多数据的时候不推荐 * Class CustomPaginate * @package App\Tools\Paginate */ class CustomPaginate { /** * 自定义数组分页 * @param $data = 返回结果 * @param $page * @param $limit * @return mixed */ public static function paginate($data, $page = 1, $limit = 10) { if (!is_numeric($page) || !is_numeric($limit)) { return false; } $count = count($data); $data = array_slice($data, ($page - 1) * $limit, $limit); return new LengthAwarePaginator($data, $count, $limit, $page); } /** * 参数解释 对外暴露的方法 * @param $data = array|collection 切记只支持这两种 * @param $page = 当前页 * @param $limit = 每一页展示几条 * @return array|false * 返回结果为数组 * 调用实例: CustomPaginate::paginateToArray($data, $request->page, $request->limit); */ public static function paginateToArray($data, $page = 1, $limit = 10) { $isValidate = self::validate($data, $page, $limit); //验证 if ($isValidate === false) { return false; } $res = self::paginate($data, $page, $limit)->toArray(); //分页数据转换为数组 //上一页 || 下一页 => path if ($res['prev_page_url'] != null) { $prev_page = $page - 1; $res['prev_page_url'] = Paginator::resolveCurrentPath() . "?page=" . $prev_page . "&limit=" . $limit; } if ($res['next_page_url'] != null) { $next_page = $page + 1; $res['next_page_url'] = Paginator::resolveCurrentPath() . "?page=" . $next_page . "&limit=" . $limit; } return $res; } /** * 验证参数是否合法 */ public static function validate(&$data, &$page = 1, &$limit = 10) { $page = empty($page) ? 1 : $page; $limit = empty($limit) ? 10 : $limit; if (!is_array($data) && !$data instanceof Collection) { return false;//"自定义分页方法只支持数组数据和集合数据"; } if (!is_numeric($page) || !is_numeric($limit)) { return false;//"page limit 参数只支持数字"; } if ($data instanceof Collection) { return $data = $data->toArray(); } return $data; } }

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.
