The Debian developers have publicly announced their plans to migrate all of the PHP 5 to the brand new and powerful PHP 7 release, as well as to change the PHP packaging to allow co-installable versions.The announcement was made by Debian developer Ond?ej Surý a few couple of days ago on one of Debian Project's mailing lists, where he informs Debian devs about the changes made to the PHP packaging for the operating system, in the pkg-php packaging group.
In fact, PHP 7 has already made it to the unstable releases of the Debian linux distribution for those that would like to test things out. You can find out more of the specifics in this mailing list post on their implementation plans.
