I have been waiting for PHP 5.4 for months now. Even with Dartmouth it is not there in the repos. I know how to compile PHP and add it to Apache but I do not want to break things. Yeah, compiling won’t hurt but when am I going to get PHP 5.4 anyway?
Then “show others versions” and select tumbleweed package from devel:languages: php. If you trust this repo than you can use 1-click-install. It enables the whole repo. Maybe necessary for dependencies. Otherwise save only the rpm package and good luck.
