Cannot redeclare %s::%s()

Description

Each method in a class must have a distinct name. There can be not two methods with the same name.

The parent classes, or the traits, may have duplicate methods: these will be ignored.

One special case are the enumeration: the backed enumeration, with their type, import two methods to convert a value into one of the case: try and tryFrom. Then, these two methods are part of the definition of the enumeration, and it is not possible anymore to define them in the enumeration.

Example

<?php

class X {
    function foo() {}
    function foo() {}
}

enum E {
    function try() {}
    function tryFrom() {}
}

?>
