I use Yum on Fedora 11 to update my computer.
On my box, I have
[luc@zappa locale]$ php --version
PHP 5.2.9 (cli) (built: Apr 15 2009 09:30:33)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
But according to this page, my version is not supported.
I guess that I could un-install and re-install it with yum
yum remove php
yum install php
There is another way to ugrade my php ?
