"How do I install PHP via yast2?" saith the newbie. HI all. I have just installed SuSE on an older computer. I have not gotten apache running (installed it via Yast2 control center). If I install the PHP module via YAST 2 control center then apache won't run. How do I install PHP via Yast2? Thanks in advance. Regards from Denmark. Dan
