@laruence it is intended behavior to have no fatal error in this case.
The method of the class has precedence and solves the conflict explicitly.

If the class does not define a method with that name, the conflict remains 
unsolved, and you will get an error.

@gron, the second example is try to description another bug of the first 
example, 
that is , if the class have a own defined same name as trait, no fatal error 
occurred, :)

Hi Laruence:

The first example is a bug, indeed.

Why is the second example a bug?
To me it looks like the perfectly intended traits semantics, no?

and if the class have no own func method defination, the result will be:
<?php
trait T1 {
    public function func() {
        echo "From T1\n";
    }
}

trait T2 {
    public function func() {
        echo "From T2\n";
    }
}

class Bar {
    use T1 {
        func as f1;
    }
    use T2 {
        func as f2;
    }
}

PHP Fatal error:  Trait method func has not been applied, because there are 
collisions with other trait methods on Bar in /tmp/1.php on line 21

this should also be a bug. thanks :)

Hi, dmitry, could you please look at this? thanks

the problem occurrs in zend_traits_merge_functions. in that function, it will 
unique the trait methods name. 

the fix will be a big change, since we should re-implemention the whole merge 
functions mechanism, maybe add the tarit name as a suffix to method name.

thanks
