今天研究websocket的时候,发现网上很多websocket+php的demo都是要在命令行输入php -q xxx.php来启动服务端,我对php不是很熟悉,想请问以下这种场景能实现吗?
浏览器ajax请求创建socket-->服务端接收并建立socket,返回socket地址和端口,
浏览器接收到socket地址和端口,开始new websocket,与服务端建立socket链接。
另外:每个浏览器与同一服务器建立socket连接,服务端是不是就得新开一条进程??

使用命令行运行服务端,是因为这样更健壮,不要尝试以php-fpm或者apache这样WEB服务的方式建立起服务端,不切实际。
PHP编写服务端,可以考虑下用这个,http://www.swoole.com/。
一般稳定的server都要以deamon的形式运行存在。
楼上说的swoole是用C扩展实现的php socket server,类似的还有workerman,workerman是基于php的pcntl实现,可以说是原生PHP实现的,共同点就是一定要以deamon形式运行server,抛开http层的apache或者nginx,直接走socket(按我的理解,是传输层的东西)。
ajax可以链接server,你可能,我是说可能,会遇到ajax跨域的问题。

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.
