Subject: php7.0: php5 to php7.0 regression: undefined function xml_parser_create()

Date: Fri, 08 Apr 2016 21:06:00 +0200

Package: php7.0
Version: 7.0.5-2
Severity: normal

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

In my effort to test my package cacti against php7.0 I found the following
regression. With php5 the page http://localhost/cacti/graphs_new.php works fine
and as expected, with php7.0 I get a 500 Internal Server error response due to
undefined function xml_parser_create. As far as I dived into this, php could
just support that and as the Debian package has done so for an extremely long
time, I think it is a regression not to do so with php7.0.

[Message part 1 (text/plain, inline)]

Thanks to Steve Langasek (on #ubuntu-devel) I learned that this is on
purpose and this is now put into php-xml. So cacti just needs an
additional dependency on php-xml (confirmed).

Sorry for the noise.

Do you have: `apt-get install php-xml` installed?
