[ciapug] php 5

You can do just about anything with PHP 4.3 you can do with PHP 5.1, but you
have to write more code with PHP 4.  I think PHP 5.2 is available, but I
think I'm still using PHP 5.1.

The syntax is not a whole lot different.

You did not mention OOP, but the major difference between versions 4 and 5
is how objects are passed to functions.  In version 4 they are passed by
value and you have to use the "&" operator to tell PHP to pass them by
reference.  In version 5 the default behavior is to pass objects by
reference (which is how Java and C# do it).

I regularly convert PHP 4 code to PHP 5 and PHP 5 code to PHP 4.  I think
upgrading from PHP 4 to PHP 5 and converting code back and forth is fairly
easy.

Subject: [ciapug] php 5

So... I just got a new workstation setup and running rhel 5.  I'm
getting ready to port/partially rewrite a php 4.3x application to php 5.

I'm wondering... have any of you rewrote an existing procedural
application in php 5 and then did something crazy like try and run it on
php 4.3x  (The redhat php version numbers are slightly differant then
those from the php folks)

I really don't need any new functionality, but it is, at the very least
time to move to php 5.

Any thoughts?


:) Dave
