PHP and Javascript are two entirely different things. Javascript typically runs on the client side (mostly in your web browser), PHP on server side (i.e. the web server), although NodeJS has become quite popular which allows you to run Javascript anywhere including on the server or outside of the web browser. But that's not what it was originally made for.
Anyway, there is no "right" answer here.
Java can be a good start because it's used a lot, its C-like syntax is used by a lot of other languages as well, and it's easier than C/C++. C# can also be used.
But it can also make a ton of sense to start with things like Python or Ruby because their syntax is a lot cleaner and you can read and write code much quicker and with fewer hassles, which also helps a beginner a lot.
C/C++ are also very important languages that allow close to the metal programming which is important in e.g. game engine programming, OS/driver programming or embedded systems programming. So it can be very important when you want to go that route, although it has a lot of added complexity over the others mentioned above of course, and this complexity might make it a worse choice for writing regular applications because you'll likely produce code with much more bugs and security holes.
You can also make it dependent on what you want to do later on. Personally, I started with typical scripting languages (first Perl 5, then Python 2 back in the day) because I never write "big" programs, just small ones, and a lot of scripts (professionally and personally).
