Upgraded php from 5.6.30 to 7.0.32, civicrm still gives PHP out of date error

Question

I upgraded php from 5.6.30-0+deb8u1 to 7.0.32-1~dotdeb+8.1 and civicrm is still giving me a php out of date error.

When I run php -v it says 7.0, but civicrm still thinks I'm on 5.6.

Do I need to purge php 5.6 if php -v tells me I upgraded to 7.0?

Answer 1

It depends on your hosting server. It is usually possible to specify different PHP versions for command line (eg. php -v) and php that is used by your web server. If you have no need for PHP 5.6 then I suggest you remove it and that trigger everything to use PHP 7.0. Otherwise you'll need to look at your webserver/php configuration to make sure PHP 7.0 is selected as default. Also, worth noting that PHP 7.0 is end of life soon, worth going to PHP 7.1 if available.

Answer 2

OK, so 2 steps

1. Disable php5 and enable php7 in apache sudo a2dismod php5 sudo a2enmod php7 (maybe php7.0 sudo service apache2 restart

2. civicrm needed me to install a few php extensions -

sudo apt-get install php-xml php7.0-gd php7.0-imap php7.0-mbstring memcache php-curl

sudo service apache2 restart

pretty much did the trick.
