Use of undefined constant DATE_RFC2822

问题

I'm trying to send emails with the cakephp mail component.

This is working well but I got this notice in debug mode:

Notice (8): Use of undefined constant DATE_RFC2822 - assumed 'DATE_RFC2822' [CORE/cake/libs/controller/components/email.php, line 599]

It's pretty embarassing since emails have no "send date" when received.

I haven't modified anything in this component or in any file of the cakephp core (except the configuration files obviously)

Any idea?

回答1:

Okay, this constant is used to format dates, cakephp mail component try to use it but it seems to be undefined, probably your version of PHP does not support it.
