What version of WP officially supports php 5.3.2?

You should be okay moving to that server.

WordPress only specifies the minimum PHP requirement (which for 3.0.1 is PHP 4.3 or greater – in the Spring 2011 the minimum will be PHP 5.2)

Hi there Michael –

You are saying that WordPress code is compatible with PHP 5.3 across all versions of WordPress?

I am actually a web host and in a dry run of upgrading PHP from 5.2.14 to 5.3.2, there were many errors on a number of WordPress sites due to features and functions being deprecated in PHP 5.3.x

In some cases it was clear that the errors and/or warnings were coming from plug-ins or templates, but there were several sites where that did not appear to be the case.

Can you please clarify?

Thanks.

Mike

Hmm, maybe you can make more sense of this than I can:

https://www.google.com/search?q=wordpress+trac+php+5.3.2

Nope – I cannot. I have done various searches and have not found anything anywhere that says – as of version ??? we are now supporting PHP 5.3

That is what I need – something definitive.

Thanks.

Don’t know if that really exists. But if you are getting errors with 5.3 you might want to report that to trac.

This is not a bug. PHP 5.3 discontinues various functions, features and directives that are in previous versions. If, for example, WP 2.6.5 does not support PHP 5.3, which it likely does not – then it is not a bug – it is a need to upgrade the client from that version to the version which adds PHP 5.3 support.

What I am seeking to find out is which version of WP added PHP 5.3 support, if any. The software would have had to undergo some recoding if it used discontinued directives/functions, which it appears very clear that it does.

This is not much different than software which works on Windows XP but doesn’t work on Windows 7. Same OS, different versions.

Thanks.

Well WordPress seems to run on sites using 5.3.2 — such as https://www.evilzenscientist.com/

Maybe someone else can add some other comment here.

Thanks – that’s helpful, but I have little doubt certain versions are compatible. As a web host, what I specifically need is to be able to determine which clients have WordPress installations that will not work when we upgrade to PHP 5.3.2. I also need to be able to provide them guidance of which minimum version they will need to be on.

Since the coders had to code the product to be compatible at some point, I’m sure there must be some record of this information.

Thanks.
