Hi, all -

Hoping someone can help me with this..I have a client who has a webiste
with a number of  php3 scripts in it, and we're having a spate of
problems relating to migration to php4.

1) I need to know what needs to be done to convert php3 scripts to be
compatible with php4.
   These are scripts largely to do with counters, statistics, date &
time functions, and the    like. What needs to be done to their
extensions as well?

2) Not having access to that info at the time, we decided to go back to
php3 - and then ran     into a host of security issues re visibility of
the html directory. The requisite
   libraries were there, apache was configured to work with php3, and so
forth. If anyone
   can explain how security issues arose, and give me some faint clue as
to how to prevent
   that from ever happening again,I will try to send maple syrup. 8) 

3) Can anyone begin to explain the rationale for making php3 and php4 so
utterly  
   incompatible?

Thanks in advance, 

Alpha
