Will there be any measurable performance difference when passing data as values instead of as reference in PHP?

I\'m just learning c++, and coming from c, some function calls I\'m seeing in the book confuse me: char a;
Is there a case where pass-by-reference is more expensive than pass-by-value in C++? If开发者_JS百科 so, what would that case be?Prefer passing primitive types (int, char, float, ...) and POD structs
We have a C++ library which uses a struct containing an STL vector of structs, like so: struct Params {
From the lectures notes of a course at university, on \"call-by-value\": void fun(int *ip) { *ip =100; } called by
We\'ve created a caching layer to our J2EE-application. In this instance we use Ehcache. This has created a few challenges.
