PHP不会加载php.ini文件

I have set up a MAMP server on my local computer.

The server runs fine, no problems, but I need to install the mcrypt extension on PHP as I need to install Laravel.

I've been following this tutorial:

http://coolestguidesontheplanet.com/install-mcrypt-php-mac-osx-10-9-mavericks-development-server/

I have an issue with the last step. When I create a new php.ini file using the following Terminal command, PHP refuses to run at all.

sudo cp /etc/php.ini.default /etc/php.ini

Basically with no php.ini file in the etc/ folder, the PHP works fine (PHP info pages load, sites using PHP run fine), but when it's in place, no PHP works and loading a PHP info page returns a blank white browser window.

Am I missing something?

OK I managed to figure out the issue, here's the solution for anyone stumbling on this in the future.

short_open_tags was disabled in the php.ini file. I simply enabled this, saved the file to the /etc folder and rebooted the Apache server and it works great now. I needed to modify the php.ini file again to add the mycrypt extension but now works great.
