I will "try" upgrading to PHP 5 in TM.
Question: is there any thing else that i need to know besides the instructions at TM/Bundles/PHP/Help/4.1
my plan of action is to upgrade to OS 10.5 when the DVD gets here this friday.
and the various upgrades thru the Apple server.
install PHP 5 on the machine via  entropy.
follow the instructions as given, TM/Bundles/PHP/Help/4.1
see what kind of mess entropy and MAMP can make, yes i will have the servers shut off.
and go from there.
If any one could bring me to notice anything i do not see please let me know.
Thank you
i found universal install DVD of 10.5 at hardcoremac that is affiliated with yahoo business.
