Here are updated packages in the Yum repository:

• PHP 5.5.0 for CentOS/RHEL 6.4 and 5.9 changelog

The PHP 5.5.0 release is out now for CentOS/RHEL 5 on the Webtatic Yum repository as well as CentOS/RHEL 6. It took a little longer to prepare the EL5 version due to resolving ICU requirements, as PHP 5.5 only supports ICU >= 4.0. There is a new set of packages icu42 / libicu42 now included for this.
