I modify my php.ini file for it expresses error messages. PHP, on
loading, claimed beeing unable to load a few modules though available in
the appropriate directory; commenting out the loading of these modules
in the php file fixed the problem.
These modules were
; extension=php_oci8.dll
; extension=php_oci8_11g.dll
; extension=php_pdo_oci.dll
; extension=php_sybase_ct.dll
