Installing PHP4 - REHL 5

Hi All,

Is there anyone facing a problem installing PHP 4 at Red hat Enterprise 5?

I paid for the red hat update subscription and when i look at the website it seems PHP4 is only for Red Hat enterprise 4.

My web server only can use PHP 4 and i cant use PHP 5.
Am i going to have an issue if i install PHP4 for REHL 4 in to REHL5?

Any advise?

Thank you
