config

i am running suncobalt 550 linux system, php.ini and also parse html as php
1)

when i try to use ibase_pconnect()

to access a remote interbase database, i got this error

Fatal error: Call to undefined function: ibase_pconnect() in

i went to the php.ini

change the set up from

;extension=interbase.so
;extension=pgsql.so

to

extension=interbase.so
extension=pgsql.so

and i saved the change of php.ini.

but the page still give me error message

Fatal error: Call to undefined function: ibase_pconnect() in.



2)

i also want to parse html as php, so i went to the apache conf file and
below the lines

AddType application/x-httpd-php4 .php3
AddType application/x-httpd-php4 .php4
AddType application/x-httpd-php4 .php

i add

AddType application/x-httpd-php4 .htm
AddType application/x-httpd-php4 .html

and saved the changes

but the html parse to php is still not working.

3)

except change these ini or conf files, what else i need to do? do i need to
restart the process somehow?

thanks. help please!
