If you are using Apache2 SAPI ( libapache2-mod-php*), you need to disable PHP 7.0 after you install libapache2-mod-php5.6 by running a2dismod php7.0 and enable PHP 5.6 by running a2enmod php5.6. Ubuntu 16.04 has only PHP 7.0 in the repositories, you can use ppa:ondrej/php to add support for PHP 5.6 using similar naming scheme (e.g. Your question lacks important details, so I will answer more broadly.Īssuming you are using packages, there are some important details:Īpache2 can be configured to use either apache2 SAPI using libapache2-mod-php7.0 package or FPM SAPI using php7.0-fpm with mod_proxy_fcgi. You can also quickly check which yours is using by running php -v. Sudo ln -sfn /usr/bin/php5.6 /etc/alternatives/php Sudo a2dismod php7.0 & sudo a2enmod php5.6 & sudo service apache2 restart Or from php7.0 to php5.6: # For php in web apps
Sudo ln -sfn /usr/bin/php7.0 /etc/alternatives/php Sudo a2dismod php5.6 & sudo a2enmod php7.0 & sudo service apache2 restart To switch from php 5.6 to php 7.0 you need to do two things: # For php in web apps Installing both php5.6 & php7.0 was clean in my case: no complain of issues, etc. You can do so with: sudo add-apt-repository apt-get apt-get install php7.0 php5.6 php5.6-mysql php-gettext php5.6-mbstring php-xdebug libapache2-mod-php5.6 libapache2-mod-php7.0 php5.6-curl php5.6-gd php5.6-mcrypt php5.6-xml php5.6-xmlrpc Therefore, in some cases, it might be sensible to have both php 7.0 and php 5.x, so that you can choose which version to use for your needs at any time. Ubuntu 16.04 comes with php 7.0, and some php applications might still fail with php 7.0.
Sudo apt-get install php7.0 php5.6 php5.6-mysql php-gettext php5.6-mbstring php-mbstring php7.0-mbstring php-xdebug libapache2-mod-php5.6 libapache2-mod-php7.0Īpache: sudo a2dismod php5.6 sudo a2enmod php7.0 sudo service apache2 restartĬLI: sudo update-alternatives -set php /usr/bin/php7.0Īpache: sudo a2dismod php7.0 sudo a2enmod php5.6 sudo service apache2 restartĬLI: sudo update-alternatives -set php /usr/bin/php5.6 So if after you follow the below instructions you face this situation, you may need to disable the proxy_fcgi apache module: sudo a2dismod proxy_fcgi proxy sudo service apache2 restartĪctually is not required to remove php7.0, you can install php5.6 together ( also because you will have dependency problem with phpmyadmin package that required php7.0)Īssuming libapache2-mod-php is a suitable way to enable PHP in Apache for you, you can proceed in this way: sudo add-apt-repository ppa:ondrej/php Today I got again problem with PHP 7 running despite I have disabled php7.0 apache module: phpinfo was showing php 7 using fastCGI.
