<? phpinfo() ?>
Very rare since a MySQL client library is distributed with PHP and built into PHP by default.
However, it is possible to build PHP without MySQL support. Some possible fixes:
apt-get install php-mysql
rpm -Uvh php-mysql-4.2.2-1.i386.rpm
./configure --with-mysql=shared,/usr
cp modules/mysql.so /usr/local/lib/php
extension_dir=/usr/local/lib/php
extension=mysql.so
