While diving into the core features of CodeIgniter, I came across a query regarding the declaration of a variable.
static $_classes = array();
As highlighted in this post, the purpose of this variable is to cache class objects.
I'm confused because the variable is declared within the function scope,
Shouldn't it be initialized every time the load_class function is called?
Would the function look like this instead?
static $_classes = array(); // declared outside the scope
function load_class (@params---) {
// inner workings
}
Instead of
function load_class(@params---) {
static $_class = array(); // declared inside the scope
//inner workings
}
