Centos/RHEL 6: 32bit PHP package on 64bit architecture

Question

How can I install the i686 php package on an x86_64 architecture?

Answer 1

RHEL support multiarch, so you should just be able to install the i686 package with yum:

yum install php.i686

That should drag in the appropriate dependencies and everything. You may need to add the 32-bit repositories, if they aren't already included.
