Question

I have a question regarding PHP. Is there any way I could make a function, which has a dynamic number of function inputs?

For example, let’s call that function dynamic_func()

It should work in both of these cases, and also in other cases, not depending on number of functions input:

 dynamic_func(1,2,3,4)
 dynamic_func(1,2,3,4,5,6)

Thanks in advance!

I believe PHP will never complain if you pass more arguments than those expected by a function. E.g.:

<?php
function foo($a) {
}
foo();         // invalid (Warning: Missing argument 1 for ...)
foo('a');      // valid
foo('a', 'b'); // surprise... valid!

So you can use func_get_args() and func_num_args() inside foo() to detect how many parameters were actually passed on to that function:

<?php
function foo(/*$a*/) {
    echo func_num_args();
    var_dump(func_get_args());
}
foo('a', 'b');

Rest is up to you.
