PHP Warnings : Please help

Hi all,

I just installed php 4.3, and when i run 'php-v', the following warnings were displayed

PHP Warning: Unable to load dynamic library '/usr/lib/imap.so' -
/usr/lib/imap.so: cannot open shared object
file: No such file or directory in Unknown on line 0

PHP Warning: Unable to load dynamic library '/usr/lib/mysql.so' -
/usr/lib/mysql.so: cannot open shared object
file: No such file or directory in Unknown on line 0

May I ask what's causing the warnings, the implications and what can I do to resolve it?

Thanks!
