pdo_mysql.so:undefined Symbol:pdo_parse_params in Unknown on line 0

When I use YII2 to build a website, I often get the following warning when I open the website:

PHP warning:php startup:unable to load Dynamic Library '/usr/lib/php5/20121212/pdo_mysql.so '-/usr/lib/php5/20121212/p do_mysql.so:undefined Symbol:pdo_parse_params in Unknown on line 0


Workaround:

Remove and purge the Php5-common package. That is, remove and merge the Php5-common installation package.

However, when you do this, the other packages will be removed, so to remove the Php5-common, the corresponding removal of the package is written down and will be reinstalled later.

Note: The following command will delete all PHP5 related configuration files.

apt-get--purge Remove Php5-common

Then remove the Php5-common when removing the relevant package to re-download the installation.

apt-get Install Php5-common etc.
