Install PHP5 on Ubuntu 17.04 Zesty Zapus

Edit on GitHub

System Administration
2 minutes

(Theoretically) You can install both PHP5 and PHP7 and switch between them.. If you only want PHP5, add the repo, install the packages for PHP 5.6 and end it there.

WARNING:
  • This leads to PhpMyAdmin not working if you install it afterwards..
  • Both versions working has not been tested in production.
  • If you check PHP version on system, php --version, it still shows PHP 7.0

add repo

There are no PHP 5.x packages in Zesty repositories. Only in the PPA, so you need to add the repo

1sudo add-apt-repository ppa:ondrej/php
2sudo apt update
NOTE: if you get
  sudo: add-apt-repository: command not found

then install the software-properties-common package. For my Ubuntu version (Precise Pangolin, 12.04 LTS), I also had to install the python-software-properties package:

  sudo apt-get install software-properties-common -y

install packages

1# PHP 5.6
2apt-get install php5.6 libapache2-mod-php5.6 php5.6-cli php5.6-common php5.6-curl php5.6-dev php5.6-gd php5.6-intl php5.6-mcrypt php5.6-mysql  php5.6-recode php5.6-xsl php5.6-pspell php5.6-ps php5.6-imagick php-pear -y

Switch PHP version ( Apache ):

from php5.6 to php7.0:

1sudo a2dismod php5.6 ; sudo a2enmod php7.0 ; sudo service apache2 restart

from php7.0 to php5.6:

1sudo a2dismod php7.0 ; sudo a2enmod php5.6 ; sudo service apache2 restart
