说明：本文主要学习Laravel的Artisan Command、Task Scheduler和Mail相关知识。做一个简单的小demo，用来定时发邮件。。走完整个流程最多只需一小时。同时，作者会将开发过程中的一些截图和代码黏上去，提高阅读效率。作者的开发环境是本机的MAMP集成软件，PHP7.0，Laravel5.2.*。
Laravel中Artisan Command内容可以参看： 服务 —— Artisan Console ，Mail邮件服务内容可以参看： 服务 —— 邮件 ，以及Task-Scheduler任务定时器可以参看： 服务 —— 任务调度 。
Artisan Command
新建一个artisan command：
php artisan make:console SendEmails --command=emails:send
并在AppConsoleCommandsSendEmails.php文件中添加代码：
class SendEmails extends Command{ /** * The name and signature of the console command. * * @var string */ protected $signature = 'emails:send'; /** * The console command description. * * @var string */ protected $description = 'This is a demo about sending emails to myself'; /** * Create a new command instance. * * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * * @return mixed */ public function handle() { $this->info('I am handsome'); $this->error('I am not ugly'); }} 写上$description和handle()方法，$description变量用来显示命令的说明，handle()用来处理命令，然后在AppConsoleCommandsKernel.php中注册命令：
protected $commands = [ // Commands\Inspire::class, Commands\SendEmails::class, ];
好，这下可以在终端输入php artisan查看并执行命令了：
邮件服务API驱动需要安装guzzlehttp/guzzle这个包，在项目根目录下：
composer require guzzlehttp/guzzle
然后在.env文件中配置下邮件驱动和用户名密码：
然后修改下handle()方法：
/** * Execute the console command. * * @return mixed */ public function handle() {// $this->info('I am handsome');// $this->error('I am not ugly'); $user = [ 'email' => 'XXX@XXX.com',//一个有效的邮箱接收地址 'name' => 'liuxiang', ]; $status = Mail::send('emails.send', ['user'=>$user], function($msg) use ($user){ $msg->from('XXX@XXX.com', 'liuxiang email');//一个有效的邮箱发送地址 $msg->to($user['email'], $user['name'])->subject('This is a demo about sending emails to myself'); }); if(!$status){ $this->error('Fail to send email');exit; } $this->info('Success to send email');exit; } 发送的内容在视图emails.send里，新建resources/views/emails/send.blade.php文件:
<html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- 上述3个meta标签*必须*放在最前面，任何其他内容都*必须*跟随其后！ --> <title>Bootstrap Template</title> <style> html,body{ width: 100%; height: 100%; } *{ margin: 0; border: 0; } .content{ text-align: center; margin: 50px; } </style> </head> <body> <div class="container"> <div class="row"> <div class="col-xs-12 col-md-12"> <p class="content">This is a email by Laravel Artisan Command</p> </div> </div> </div> <script> </script> </body></html>
一切准备OK，在项目根目录运行邮件发送命令吧，然后会收到邮件发送成功打印：
然后接收的邮箱会收到邮件：
It is working!!!
Task-Scheduler
每次手动发邮件毕竟不太爽啊，可以利用系统的定时器crontab定时发送，Laravel里有任务定时器可以玩一玩。修改app/Console/Kernel.php文件：
/** * Define the application's command schedule. * * @param \Illuminate\Console\Scheduling\Schedule $schedule * @return void */ protected function schedule(Schedule $schedule) { // $schedule->command('inspire')->hourly(); //$schedule->command('emails:send')->everyFiveMinutes(); $schedule->command('emails:send')->everyMinutes(); } 在终端输入 crontab -e 添加一个cron条目：
* * * * * php /Applications/MAMP/htdocs/laravelemail/artisan schedule:run 1>> /dev/null 2>&1
然后程序每隔一分钟发个邮件过来：
总结：本文主要以Laravel的Artisan Command、Mail和Task-Scheduler做一个好玩的小demo，来定时发发骚扰邮件，哈哈。还挺好玩的，可以试一试。。嘛，过几天想结合设计模式来聊聊Laravel，到时见。
Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AMLoad balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AMAlternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
Define the term 'session hijacking' in the context of PHP.Apr 29, 2025 am 12:33 AMSessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,
Is PHP a case-sensitive language?Apr 28, 2025 pm 04:55 PMPHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
