Php - Your PHP installation appears to be missing the MySQL extension which is required by WordPress

Question

For me to fix the error occurring below, what should I do? 

Your PHP installation appears to be missing the MySQL extension which is required by WordPress.

I have been using a telnet connection with my NAS and have installed FFP 0.7. 

My php.ini is in: ffp/etc/php.ini and I removed my comments on everything I thought to be of use.

Below is a part of my php.ini file;

;If you wish to have an extension loaded automatically, use the following 
; syntax: 
; 
; extension=modulename.extension 
; 
; For example, on Windows: 
; extension=msql.dll
; 
; ... or under UNIX: ; extension=msql.so 
; 
; ... or with a path: 
; extension=/ffp/lib/extensions/no-debug-non-zts-20100525/mysql.so 
; 
extension=php_mysql.dll 
extension=php_mysqli.dll 
extension=php_pdo_mssql.dll 
extension=php_pdo_mysql.dll 
extension=php_pdo_oci.dll 
extension=php_pdo_odbc.dll 
extension=php_pdo_pgsql.dll 
extension=php_pdo_sqlite.dll 
extension=php_pgsql.dll 
extension=pdo.so 
extension=pdo_sqlite.so 
extension=sqlite.so 
extension=pdo_mysql.so

The issue I am facing constantly is that when I run in phpinfo(), I see the module MySQLi activated but not MySQL. MySQL is working as expected just as PHP and Lighttpd web server. I do have my phpmyadmin working which is on a Zyxel NSA310. Additionally, when mysqld starts, it creates a shortcut from my root to: ffp/opt/mysql.. and every time I restart my NAS the shortcut is deleted. Does anyone know a trick in order to solve this?
