Does the order of the declaration matter?
trait THello1 {
public $foo;
}
trait THello2 {
private $foo;
}
trait THello3 {
protected $foo;
}
class TraitsTest {
use THello1;
use THello2; // E_NOTICE: TraitTest conflict, THello2(private $foo)
ignored, already declared THello1(public $foo)
use THello3; // E_NOTICE: TraitTest conflict, THello3(protected
$foo) ignored, already declared THello1(public $foo)
}
class TraitsTest2 {
use THello3;
use THello2; // E_NOTICE: ..
use THello1; // E_NOTICE: ..
}
It could be that the first property 'wins' and an E_NOTICE is raised about
the property conflict.
Result:
class TraitsTest {
public $foo;
}
class TraitsTest2 {
protected $foo;
}
It would seem to fit php, though I'd be happy with simply E_FATAL until
people start using traits
The same for:
trait THelloA {
public $foo = 'a';
}
trait THelloB {
public $foo = 'b';
}
class TraitsTest3 {
use THelloA;
use THelloB; // E_NOTICE: TraitTest3 conflict, THelloB(public $foo)
ignored, already declared THelloA(public $foo)
}
class TraitsTest4 {
use THelloB;
use THelloA; // E_NOTICE: TraitTest3 conflict, THelloA(public $foo)
ignored, already declared THelloB(public $foo)
}
class TraitsTest5 {
public $foo = 'c';
use THelloB; // E_NOTICE: TraitTest3 conflict, THelloB(public $foo)
ignored, already declared TraitsTest5(public $foo)
use THelloA; // E_NOTICE: TraitTest3 conflict, THelloA(public $foo)
ignored, already declared THelloB(public $foo)
}
