New to mac and trying to define a php.ini file.

Hi. Where do I put my php.ini file for a MacBook Air? I've only had it 2 days and having trouble with the date.timezone setting. I've also had to install xampp (recommended - no idea about it) for Apache with PHP. Different versions of PHP now installed. Default from command line is PHP 5.3.6 with Suhosin-Patch (cli) (built: Sep 8 2011 19:34:00) The one that XAMPP installed is 5.3.1 and I've found the ini file for this is in /Applications/XAMPP/xamppfiles/etc/php.ini How, can or should I upgrade my PHP to a later release? Oh the joy of Windows Binaries!!!! Or should I just be looking somewhere else? -- Richard Quadling Twitter : EE : Zend : Fantasy Shopper @RQuadling : http://e-e.com/M_248814.html : http://bit.ly/9O8vFY : http://fan.sh/106/5tw
