Moving from PHP5.6 to PHP7 with Prestashop 1.6.1.18

[seanr22a]

I want to upgrade from PHP 5.6 to PHP7 on my server but doing so I get 500 Internal Server Error in both front and back office. Turning on debug I see this:

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /volume1/web/prestashop/classes/db/MySQL.php:51 
Stack trace: #0 /volume1/web/prestashop/classes/db/Db.php(319): MySQLCore->connect()

#5 /volume1/web/prestashop/adminxxxxxxxx/index.php(36): require('/volume1/web/pr...') 
#6 {main} thrown in /volume1/web/prestashop/classes/db/MySQL.php on line 51

 I went back to PHP5.6 again and everything running fine. Any ideas ?

the mysql driver is no longer supported in PHP 7.

you will need to ensure that either the pdo_mysql or mysqli extensions are installed and enabled for your PHP 7 installation.  you should work directly with your hosting provider if you are unable to do this yourself.

I finaly got the time to try your suggestion. I enabled the same extensions in PHP7 as in PHP5.6 and now it's working! Many thanks for pointing me in the right direction.
