PHP

PHP 5.2.x installation
php-pear, and php-sqlite2 will conflict with this if you try to do a normal yum upgrade. Try as I might, I cant seem to get the newer php-pear to be recognized by the older as an update event.
To upgrade to PHP 5.2.2 on CentOS4, while running php-4.3.x:
Step 1)
yum remove php-sqlite2
Step 2)
yum install php-pear
Step 3)
mv /etc/php.ini.rpmnew /etc/php.ini
