#3997 (ok 4.0.7) Call to undefined function PMA_DBI_num_rows()

[Alexander Schuch]

PHP Fatal error: Call to undefined function PMA_DBI_num_rows() in /opt/pma/phpMyAdmin-4.0.4-english/libraries/navigation/Nodes/Node.class.php on line 408

I had PHP PDO installed, but no drivers. After I installed pdo-mysql, it works again.

Suggestion: Show an error if PDO is not installed or if no database drivers for PDO are installed.

just try "apt-get install php5-mysql"

This is what I did and phpMyAdmin thereafter works of course. Still, causing a PHP Fatal Error and rendering a white page is not considered best practice.

But phpMyAdmin does not support PDO. However, a warning was supposed to show up (it's looking for mysqli by default).

[Alexander Schuch]

On Ubuntu, php5-mysqlnd provides pdo_mysql, mysqlnd, mysqli and mysql. Without that package, no MySQL connectivity is present at all. And in this case, a blank page is shown.

Fixed reporting of this error in git - now phpMyAdmin will properly show error message.
