    PHP 5 or PHP 4 compatible codes

    Kinda OT. I haven't yet moved to PHP5. But, interested to know how
    many of you _really_ started using it or moved? Are you doing any
    compatible tweaks specifically for PHP 5 (forward compatible) or PHP 4
    (backward compatible)?

      Basically, if you code for PHP4, it will work in PHP5. However, if you wish
      to take advantage of the full PHP5 abilities, scrap backward compatibility.

          So, are you writing codes with any compatibility care?

              You should consider compatibility if you distribute your software as very
              few web servers are migrated to PHP5, which is still not recommended for
              production server at this stage. If you own your own server, I dont see any
              need to do so.

                  This is a good advice. For the time being, use PHP5 only when your
                  application is to be run on a server that you have complete control over,
                  and even then only for non-critical applications. I have PHP5 on my own dev
                  computer both at home and ad work, and am testing its details and features,
                  but all our applications are still developed in PHP4. But when the Great
                  Switch To PHP5 (TM) comes, I'll have a head start.

                      I've only done very brief testing (an hour or two) on the 5.0.0 release, and
                      got Mysterious Crashes when using Oracle. Probably just teething troubles, but
                      it's put me off for the moment until I get a bit more time to trace it back.

                          One of the things you need to be careful of is not to depend on passing by
                          value. In PHP4 if you pass an object and modify it, a copy is modified. If
                          you run that code in PHP5 it will modify the original variable and that may
                          not be a desired effect if you depended on that variable later on in your
                          PHP4 script.

                          One way to improve PHP5 compatibility is to avoid depending on passing
                          objects by value; if you do pass an object in PHP4, make sure the function
                          you are passing it to has a '&' in front of the argument, so that you are
                          sure you are working on a reference.

                              So, this force us to write forward compatible codes?

                                  This mean PHP5 still has lot of bugs
                                  I dont have any problem with PHP5 and Oracle 9 on Linux
