What PHP4 version is best?

[chris8lunch]

Version 4.3.11
Version 4.4.1
Version 4.4.2
Version 4.4.3
Version 4.4.4

Which one is the best one? Why? I use 4.4.4 just because its the latest PHP4.. And I'm still not understanding the concept of PHP4 and PHP5, why would you make a new PHP version that doesn't support others?

Thanks in advance.

On the latest version of php 4 is there many security fixes. It is the best to use this version.

The difference between php4 and php5 is that on php5 some features are removed or added. PHP supports this 2 versions because not all hosting companies are over to php5. The must of the php sites are not yet compatible with php5.

To further note, running php4 and php5 on the same box is also
an option.

If you're running php v4 you should only be running v4.4.4 - anything older has some serious security vulnerabilities. PHP v4.4.4 laso has security issues, but the PHP developers haven't bothered releasing a fixed release version as yet (they seem to leave it months).

There're two versions for the reasons rachweb points out - php5 is not backwards compatible and will break many scripts written for php4. It's another example of the php developers not considering their own community.

It's been a feature of that languages development from its inception, unfortunately.

Don't you think that maybe they don't want to sacrifice performance for backward compatibility?


Intel had done that and they ultimately came to conclusion that they'll need to start from scratch with new architecture.

There's no reason wat all that they should need to make any such sacrifice. Backwards compatibility is a fundamental requirement of any serious programming language.
