Hi there ..


Since the Final release of PHP 5 in 13-Jul-2004 System administrators and Programmers have been upgrading to PHP5 .. Now those who have upgraded right after the official release has been facing a lot of problems with backward incompatibility and with commercial products that are written in PHP and are not working as a result of the upgrade .. and of course the easiest solution was to switch back to PHP4 !

on the other hand I personally needed PHP5 in only one application that required the use of a GD2 Library function called ImageFilter

While there are a luandry list of applications that are not running correctly under PHP5 including Modern Bill and PDF lib and a lot more ...

Now the questions is. Is it too soon to upgrade to PHP5 ? or it's the right time ?

and if most the developers sticked with PHP4 to avoid the problems in php5 won't this result in a delay in fixing the commercially available programs and scripts to work with PHP5 ?

i have had php 5 since about 1month after release.. personally no problems but also i dont use other then self written code too much

this question is the analogous to "is it the time to switch to apache 2 or it's just too soon?". you know, php 5 offers you more robust object oriented design. backed with zvm 2, php 5 quarantees a faster environment which would result in faster code execution. oo programming in php 4 is a bit slow since one can't specify function and variables inside a class. in php 5 you can define static function, private properties, protected methods, lazy initialization, etc. also, php 5 provides interface for your classes to make all functions bound to it. the existence of singleton and factory method can avoid you from creating multiple instances of a certain class, by checking object existence and creating object only when you want to.

php 5 is almost a complete rewrite thus giving better codes and structures. however, bc has been common issue which results most php4 codes can still run on php 5 environment (not conversely).

there is time that people will switch to php 5. maybe it's too soon because it's not so popular. but when php 5.1.0 is released (which is still under development now) i'm sure it's time for developers to switch their php and get more involved with php 5.

sctually, I am one of the people who upgraded right after the release but didn't really face any problems, actually no problems at all, and I loved upgrading since php 5 has alot more advanced features in the OOP area...
