Undefined function mysql_connect()

Question

I have ran aptitude install php5-mysql (and restarted MySQL/Apache 2), but I am still getting this error:

Fatal error: Call to undefined

Answer 1

My guess is your PHP installation wasn't compiled with MySQL support.

Check your configure command (php -i | grep mysql). You should see something like '--with-mysql=shared,/usr'.

You can check for complete instructions at http://php.net/manual/en/mysql.installation.php. Although, I would rather go with the solution proposed by @wanovak.

Still, I think you need MySQL support in order to use PDO.
