I have to admit, I'm still junior, but the thing that gave me most problems and still gives me some is the passage by reference.

I code mostly (almost exclusively) in PHP, and this concept is really the dumbest thing that gives me proble. I mean like "some vars are passed by reference by default, some aren't, but you can add & before some to force passing by reference" bla bla bla.

So in the end, I avoid using passing by reference and find other solutions.

stuff ;)

the concept you describe is the one used by java and many other languages :D and it's about memory, space and the GC. Basically every Object is a reference. we could argue about that there is no stack in PHP and why the memory handling - hence - is rather difficult and how the GC works but the logic is pretty common that objects are references since copies are costly in space and time :)

I know, I just get confused everytime I have to use it, and every time I see it in tests. Most of the time I get the answers wrong on this subject. I can answer pretty much everything else, I got good grades, and good results with my devs, everything is working fine. Except reference.
