Which version of PHP (PHP4 and PHP5) do you use and why?

I don't think many people would be using PHP4 these days. That is way too old. I personally don't care the exact version of PHP5, there is only very small rare cases of compatbility issues, which shouldn't affect a normal site. Generally, its not a bad idea to host with a web host that uses reasonably new version of all kind of server software.

While it's true that WordPress' requirements are PHP 4.3 or higher, you will get maximum effectiveness if your hosting service supports PHP 5. I highly recommend that you enable PHP 5 support on your hosting service *before* installing WordPress. If you're already running WordPress, then you can quite likely switch to PHP 5 without any modifications, or very minimal adjustments in some cases.

php is the old one try some new like php5. :)

PHP 5 is having great options and commands.

Difference php 4 and 5

* Php 4 is the older version and not alot of commonds working on this version
* PHP 5 is the latest version it is very usefull of very easeally commond and using more function

Up-gradation is necessary so better use upgrade version .

PHP 5, Because new object-oriented support to provide an OO interface to MySQL. On top of that, the latest versions of MySQL now enable subselects, transactions, and replication on PHP 5

PHP version 5.4.8. its based on oo concept .

I advise to use the latest stablest version and the version which suits your scripts.

See details here

I am using PHP 5.4

I choose PHP5 Because PHP5 provides a lot of new functions that make your job easier than developing in PHP4 :)

PHP 5 having lots of new function so I prefer PHP 5 in place of PHP 4.
