yum install php-pear
Step 3) Replace the PHP 4 ini with PHP 5.2.x's (if applicable)
mv /etc/php.ini.rpmnew /etc/php.ini
Step 4) Replace the php.conf with the PHP 5.2 php.conf (if applicable)
mv /etc/httpd/conf.d/php.conf.rpmnew /etc/httpd/conf.d/php.conf
Checklist
1) Source code installations of extensions, like Ioncube loader, or other extensions that have to be updated
2) php.ini settings, like memory_limit
3) execstack -c on any extensions that claim to need an executible stack (ASL users only)
Known Issues
VPS and RHEL users, If you dont use the atomic installer, you're going to miss some dependencies, like sqlite3. Have fun with that!
