How can I upgrade my PHP 5.3.1 to 5.3.2 on XAMPP Mac OS X?
Not to lead you in a different direction, but if you were using MAMP (free version) on OS X, that comes with the most up-to-date version of PHP and allows to you switch between 5.2.17 &amp; 5.4.3.

I find that MAMP is less messy than XAMPP.
