PHP 5.3.0RC2

[Phil Driscoll]

Hi

I've just been testing my installation of Squirrelmail (1.4.17) on the latest
release candidate for PHP5.3.0. It appears to work ok, except that on my
development machine (which has display_errors set to on in my php.ini)
SquirrelMail no longer works because of the output of multiple instances of a
warning message:
Deprecated: Function session_unregister() is deprecated
in ...functions/global.php on line 249
followed by the inevitable
Warning: Cannot modify header information - headers already sent by...

I'm back up and running by turning off display_errors in my apache config for
the SquirrelMail directory, but it is obviously more convenient to have
errors displayed when developing plugins.

I'm not sure of the repercussions elsewhere, but I suspect that it may be ok
to fix this by simply removing the call to session_unregister in
sqsession_unregister since this already unsets $_SESSION[$name].

PHP's session_unregister() function disappears completely as of PHP 6, so I
guess this needs to be fixed in SquirrelMail before it turns into a fatal
error.

Cheers

You're right.  Thank you for letting us know.  I've already removed it
in 1.5.2SVN, and will remove it from 1.4.19SVN after 1.4.18 is out.
