Solution 1 - Php
try
yum install php-pdo
yum install php-pdo_mysql
service httpd restart
Solution 2 - Php
Try adding use PDO; after your namespace or just before your class or at the top of your PHP file.
Solution 3 - Php
This can also happen if there is a php.ini file in the web app's current working directory. If one has been placed there to change certain settings, it will override the global one.
To avoid this problem, don't use a php.ini file to change settings; instead you can:
Solution 4 - Php
Ensure they are being called in the php.ini file
If the PDO is displayed in the list of currently installed php modules, you will want to check the php.ini file in the relevant folder to ensure they are being called. Somewhere in the php.ini file you should see the following:
extension=pdo.so
extension=pdo_sqlite.so
extension=pdo_mysql.so
extension=sqlite.so
If they are not present, simply add the lines above to the bottom of the php.ini file and save it.
Solution 5 - Php
What is the full source of the file Mysql.php. Based on the output of the php info list, it sounds like you may be trying to reference a global class from within a namespace.
If the file Mysql.php has a statement "namespace \PDO in place of PDO - this will tell PHP to look for a global class, rather than looking in the local namespace.

I had the same problem on GoDaddy. I added the extension=pdo.so to php.ini, still didn't work. And then only one thing came to my mind: Permissions
>Before uploading the file, kill all PHP processes(cPanel->PHP Processes).
The problem was that with the file permissions, it was set to 0644 and was not executable . You need to set the file permission at least 0755.
Solution 7 - Php
Its a Little Late but I found the same problem and i fixed it by a "" in front of PDO
public function enabled() {
return in_array('mysql', \PDO::getAvailableDrivers());
}
Solution 8 - Php
you can just find-out loaded config file by executing below command,
php -i | grep 'php.ini'
Then add below lines to correct php.ini file
extension=pdo.so
extension=pdo_sqlite.so
extension=pdo_mysql.so
extension=sqlite.so
Then restart web server,
service httpd restart
Solution 9 - Php
This error is caused by PDO not being available to PHP.
If you are getting the error on the command line, or not via the same interface your website uses for PHP, you are potentially invoking a different version of PHP, or utlising a different php.ini configuration file when checking phpinfo().
Ensure PDO is loaded, and the PDO drivers for your database are also loaded.

I solved it with library PHP_PDO , because my hosting provider didn't accept my requirement for installation of PDO driver to apache server.
Solution 11 - Php
If you run php with php-fpm module,do not forget to run command systemctl restart php-fpm!That will reload php-fpm module.
Solution 12 - Php
I had to run the following on AWS EC2 Linux instance (PHP Version 7.3):
sudo yum install php73-php-pdo php73-php-mysqlnd
Solution 13 - Php
If anyone getting this error in cPanel, please check the PHP version type in your cPanel. Change it, alt-php to ea-php. This setting worked for me.
Solution 14 - Php
After a long time, I finally solved it. check your folder in Cpanel to see if there is a php.ini file. if yes delete it since Cpanel will be using its own php.ini
Solution 15 - Php
For Fedora 33 you can install as follows:
Install
dnf install php-pdo
dnf install php-pdo_mysql
Restart PHP
systemctl restart php-fpm.service
