It shows an error that fun1 is not implemented for the signature of the passed
parameters.
But you could still provide a method that matches any number and type of
parameters by adding the following method declaration.
/**
* This method accepts parameters of any type and any count.
*/
public function fun1($parameters ...) {
/*
* array(3) {
* [0] => string(1) "a"
* [1] => string(2) "b"
* [2] => string(3) "c"
* }
*/
var_dump($parameters);
}
The "..." notation (making it possible to have a dynamic count of parameters of
the given type (missing typehint automatically chooses mixed)) is only allowed
for the last parameter.
So method defintions like the following one are also possible:
public function fun1(string $firstParam, string $remainingParameters ...) {
/*
* string(1) "a"
*/
var_dump($firstParam);
/*
* array(3) {
* [0] => string(1) "b"
* [1] => string(2) "c"
* }
*/
var_dump($remainingParameters);
}

Betreff: Re: [PHP-DEV] Method overloading by method signature
can your patch handle the following situation? how?
class A
{
public function fun1($a)
{
//…
}
public function fun1($a, $b)
{
//…
}
}
$a = new A();
$a->fun1('a', 'b', 'c'); // which method is called here?
