In C++ you could do like this, to ensure that the parameter you passed by reference is not going to be modified:
void function Foo(const ¶m){}
How can i do the same in PHP?
No you cant, if you want just read it create copy of that variable, but overall if you dont need references dont use them, as it looks in this case. References wont give you any performance benefits on php.
