在浏览器启动的后台执行php脚本[关闭]

Question

I am writing a php script to send mails to all the email addresses in a particular mailing list. The mails might run into thousands and the entire script can take even hours to execute. What I want is the once the user enter the mail details, body, subject etc and hits a button/link, the php script runs in background and the user is redirected to some page as soon as he hits the button/link.

In short the php script should be initiated from the browser but should run on the server even if the browser is closed.

Alternatively if a progress bar can be shown on redirected page using AJAX/Javascript but the php script should continue executing even if the browser is closed.

Answer 1

PHP is the wrong tool for the job. Set up a mailing list on a e-mail server (perhaps the same server), and from the browser hand the data to PHP via ajax, which should then send the e-mail (only once) to the mailing list.

The e-mail software will take care of sending a copy to every subscriber of the mailing list.

This is one of the most efficient ways of doing it.

Some links which may help you do more research:

Remember though, this has nothing to do with programming, and you should ask for help on some other stack exchange site (like unix or serverfault).
