overloading and overriding

[Anon]

Hi follks;

Does PHP4 supports overloading and overriding like Java?

Thanks in advance!

Yea, it does kinda. You can override any function but it is an implicit override...any function that is overridden in a child is never called in the parent, so if you have funct() on both, only child will be called.

parent.funct() will never be called and there is no way to flag a function as extends instead of overrides

What about overloading? For example, there are 2 functions:

function_a (String str, boolean b) {
....
}

function_a (String a) {
......
}

One of the function above will be called depends on the no. of args that are passed in. Will PHP4 supports something like this?

Thanks!

Not true overloading, but

function varyingparms() {

}

then call a function, I forget the name (check the docs), similar to
array = get_function_parms();

then switch based on types etc.
