PHP Warnings when trying to login on login.php

[phpinstall]

When accessing http://localhost/timetracker/login.php - I enter the admin details- user:admin, pass:secret, and nothing happens.
In the php error log i get these four lines:
PHP Warning: PHP Startup: Unable to load dynamic library 'interbase' (tried: ext\interbase (The specified module could not be found.), ext\php_interbase.dll (The specified module could not be found.)) in Unknown on line 0

PHP Warning: PHP Startup: Unable to load dynamic library 'oci8_12c' (tried: ext\oci8_12c (The specified module could not be found.), ext\php_oci8_12c.dll (The specified module could not be found.)) in Unknown on line 0

PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_oci' (tried: ext\pdo_oci (The specified module could not be found.), ext\php_pdo_oci.dll (The specified module could not be found.)) in Unknown on line 0

I am trying to install the timetracker using windows server IIS.

These warnings have nothing to do with Time Tracker, check your php.ini configuration. For example, Firebird database is not used in the application, etc.
