CentOS 5, yum update trouble about php

I update my server, and face error about xxx conflict php-5.x.x.x

Search via google, the solution is
 
   1. Remove php ( OMG, too many packet relative about php ... )    (x)
       and I find that's about openmail function ... anyway do point 2.
   2. Skip update php ( An ... I try this and it works )   (o)

all done, I still feel I need to update php, so I go into yum base folder, then force upgrade it.

About digital TV in Taiwan at my side.

I install aerial antenna to receive digital TV stream and place near by TV, it has 80%~95% quality but always have few second fragment/moasic for video, audio signal is ok ... 
May cause about too near by traffic way.  =_="
Anyway, I buy a outdoor antenna around $5usd, replace aerial antenna and some place, the
signal up to 100% and look better than old kind.
* still have a chance to make screen fragment/moasic... just few 5~10 per day.
That's interesting about big antenna near by TV, indoor behind curtain ... quality still good than aerial ... 
* Aerial cable is 5CFB, TV UHF/VHF antenna cable is RG6.
