The following updates has been released for Debian GNU/Linux 8 LTS

Package : php5
Version : 5.6.40+dfsg-0+deb8u6
Debian Bug : 805222


An update has been made to php5, a server-side, HTML-embedded scripting
language. Specficially, as reported in #805222, the ability to build
extensions in certain older versions of PHP within Debian has been
hindered by an upstream change which first appeared in PHP 5.6.15. This
update applies a fix which restores the ability to build PHP extensions
for Debian 8 "jessie" so that a forthcoming PECL extension update can be
built and released.

For Debian 8 "Jessie", this problem has been fixed in version
5.6.40+dfsg-0+deb8u6.

We recommend that you upgrade your php5 packages.
