Netbeans, despite what some people argue, is very good with both Java and PHP.

TBH I have minor snags with 8.1 so I'm holding back there. However compared to Intellij where I had a paid license and they still replied with: "just buy the next version where it will be fixed" in the Netbeans community Geertjan replied personally and helped with the troubleshooting for my unpaid product.
