Bug description: make array a traversable
Description:
------------
Traversable is an internal interface that says "I can be used in a
foreach". Since array can be used too, would be nice if array be accepted
internally in parameters that expect traversable.
Reproduce code:
---------------
<?
function acceptArray(array $t) {
echo "\n".__FUNCTION__."\n";
foreach($t as $k=>$v) {
echo "$k=>$v\n";
}
}
function acceptTraversable(Traversable $t) {
echo "\n".__FUNCTION__."\n";
foreach($t as $k=>$v) {
echo "$k=>$v\n";
}
}
$test = array("is", "array", "traversable", "too", "?");
acceptArray($test); // ok
acceptTraversable(new ArrayIterator($test)); // ok
acceptTraversable($test); // would be nice
?>
Expected result:
----------------
acceptTraversable($test); shoud accept an array, since it's too a
Traversable structure(can be used in a foreach).
Actual result:
--------------
Fatal error: Argument 1 must be an object of class Traversable
