It has been announced that WordPress version 3.2 (we are currently at version 3.1.2) will have new minimum requirements. Version 3.2 is expected to be released at the end of June 2011. At present the minimum requirements, in relation to PHP and MySQL, to run WordPress are:
the new minimum requiremets will be:

Any decent Webhost will be running versions compatible with WordPress version 3.2. If you are at all concerned it’s worth contacting your host to check the versions of PHP and MySQL they are using.
