    Does anyone have a quick guide? I don't want both so I am thinking of something along the lines of:
    - list all php5 related packages
    - remove them
    - replace them with the php7 version
    reboot

    I am using Debian 9, ISPCFG3 and nginx. Only hosting wordpress site and they are all php7 compatible.

    Install the new PHP version as an additional PHP version and then select it in the websites. The default version of the server should remain at the default version that ships with the operating system version that you use, for Debian 9, PHP 7.0 btw. and not PHP 5.

    is this the recommended best practice? I just thought that only having 1 version would help avoid problems.
    Would this be the right tutorial: https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/ ?
    Also I see already compiled packages:
    Code:
    apt-cache search php7.0
    libapache2-mod-php7.0 - server-side, HTML-embedded scripting language (Apache 2 module)
    libphp7.0-embed - HTML-embedded scripting language (Embedded SAPI library)
    php-all-dev - package depending on all supported PHP development packages
    php7.0 - server-side, HTML-embedded scripting language (metapackage)
    php7.0-apcu - APC User Cache for PHP
    php7.0-apcu-bc - APCu Backwards Compatibility Module
    php7.0-bcmath - Bcmath module for PHP
    ...
    but a search for php5 also has results:
    Code:
    apt-cache search php5 | more
    bluefish - advanced Gtk+ text editor for web and software development
    [email protected]:~# apt-cache search php5- | more
    bluefish - advanced Gtk+ text editor for web and software development
    php5-exactimage - fast image manipulation library (PHP bindings)
    php5-gdcm - Grassroots DICOM PHP5 bindings
    php5-vtkgdcm - Grassroots DICOM VTK PHP bindings
    php5-geos - GEOS bindings for PHP
    php5-lasso - Library for Liberty Alliance and SAML protocols - PHP 5 bindings
    php5-libvirt-php - libvirt bindings for PHP
    php5-mapscript - php5-cgi module for MapServer
    ...
    its php 5.6.x - can't remember the full history of this server but it might have been upgraded from Debian 8 hence php 5.6.x?

    yes. All PHP based applications on your server incl. ISPConfig expects that the default PHP version of the OS is the one that ships with the OS as these applications are tested against that versions, using a different version may lead to errors.

    As @Taleman suggested, you can get ready compiled packages from sury.org.

    Thanks for the link, I quickly skimmed it and that sounds better, thanks!
    Compiling myself was exactly what I was afraid of (I mean the overhead) hence my insistent question if I can't use apt-get :)
