I want to install the latest versions of curl, php5-xmlrpc and php5-intl extensions for php 5.4. I have the latest version of php 5.4 (installed via ppa:ondrej/php5-oldstable) so the default precise packages for the said extensions will not work. I know this because I tried that first and also tried packages for later versions such as 12.10 and 13.04.
Question is how do I install the latest versions of this extensions and where do I get them from. Any help will be appreciated.
