PHP warnings after Mavericks upgrade

After upgrading my Mac to Mavericks I've had a few small issues with machine, most of which I've resolved, however when I try to run PHP scripts at the command line I'm not getting these warnings...

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20100525/yaml.so' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20100525/yaml.so, 9): image not found in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20100525/apc.so' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20100525/apc.so, 9): image not found in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20100525/intl.so' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20100525/intl.so, 9): image not found in Unknown on line 0

The directory /usr/lib/php/extensions/no-debug-non-zts-20100525/ exists, but there is only xdebug.so & mcryt.so files in there.

I tried installing the yaml extension using pecl but it says it's already installed.

If I run sudo php -a rather than php -a then the other errors go away. What permissions do I need to set on what folder to get this working for non-admin accounts?
