Ubuntu 16.04 LTS comes with PHP 7.0. To install it, you need to run:

sudo apt-get install php

Or rather pick a specific PHP Web SAPI, most probably you need support for Apache2:

sudo apt-get install libapache2-mod-php php

Or PHP FPM

sudo apt-get install php-fpm php

If you specifically need PHP 5.x, you'll need to use ppa:ondrej/php and install, f.e. PHP 5.6 for Apache2:

sudo apt-get install php5.6 libapache2-mod-php5.6

    Sorry but in pure Ubuntu 16.04 LTS apt-get install php gives back Unable to locate package php. So frustrating! – Sliq Aug 07 '16 at 03:25

    @Sliq It must be your local configuration error since php package is available in Xenial: http://packages.ubuntu.com/search?keywords=php – oerdnj Aug 07 '16 at 06:12
  • Thanks, I think the packages on Vagrant box are broken or so (as it's the most official boxavailable) :( – Sliq Aug 07 '16 at 16:37

16.04 does not have PHP 5 in the official repositories. Install a 14.04 system, or use this PPA.

  • Oddly enough, once I got it PHP5+apache set up through that PPA, I was able to ppa-purge -o ppa:ondrej/php and I still have php5... and I can use Imagemagick and other things the normal Ubuntu PHP5 packages have. – NoBugs Jul 12 '16 at 01:47
  • @NoBugs I'd be curious to see where those PHP 5 packages are coming from; could you please pastebin the output of apt list --installed | grep php? – fkraiem Jul 12 '16 at 02:04
  • Ok looks like either they just removed, or just added them: https://www.google.com/search?client=ubuntu&channel=fs&q=php5.6+site%3Apackages.ubuntu.com&ie=utf-8&oe=utf-8#channel=fs&q=xenial+php5.6+site:packages.ubuntu.com – NoBugs Jul 12 '16 at 03:53
  • Yes, there were PHP 5 packages in Xenial when it was still in development, but they were removed some time before the release. – fkraiem Jul 12 '16 at 03:55
  • Why would they have removed them? – NoBugs Jul 12 '16 at 04:22

    Mostly because they didn't want to release (and have to support) both, see https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1522422 – fkraiem Jul 12 '16 at 04:29
