问题
I wanted to try the latest version of PHP on Kubuntu 16.04, since then, it seems I can't use pdo with mysql.
When I launch php, I have the following warning:
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_mysql' (tried: /usr/lib/php/20170718/pdo_mysql (/usr/lib/php/20170718/pdo_mysql: cannot open shared object file: No such file or directory), /usr/lib/php/20170718/pdo_mysql.so (/usr/lib/php/20170718/pdo_mysql.so: undefined symbol: pdo_parse_params)) in Unknown on line 0
I'm running
PHP 7.2.4-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Apr 5 2018 08:53:57) ( NTS )
I tried to fix with this solution : https://askubuntu.com/a/824505, but I've the same problem.
However, in the phpinfo, there's a driver found for PDO (mysql). When I check a php -m, PDO and pdo_mysql are found.
In the /usr/lib/php/20170718 and /usr/lib/php/20151012 folder, there is a pdo_mysql.so.
I don't really know what else to try. Thanks in advance for your help.
回答1:
sudo apt-get update
sudo apt-get install php7.2-pdo
回答2:
In my case I had updated from Ubuntu 16.04 to 18.04, thus PHP 7.0 to 7.2.
Turns out PHP 7.0 was still (partly) installed, and was the active PHP-FPM handler for Apache.
Commands I used to resolve this: (as root or via sudo)
service php7.0-fpm stop
apt-get remove php7.0*
service php7.2-fpm restart
service apache2 restart
Be sure to copy any INI changes you made from /etc/php/7.0 to /etc/php/7.2 though.
