Bug #33312 ReflectionParameter methods do not work correctly
Submitted: 2005-06-11 16:03 UTC Modified: 2005-06-13 11:41 UTC

Status: Closed Package: Scripting Engine problem

The ReflectionParameter::isDefaultValueAvailable() and ReflectionParameter::getDefaultValue() methods only work correctly when the method only has one parameter.

When the method has more than one parameter, ReflectionParameter::isDefaultValueAvailable() returns FALSE for a parameter that has a default value and ReflectionParameter::getDefaultValue() produces an error when trying to access the default value.

The reproducing script below works fine with the current PHP_5_0 branch. With HEAD it prints nothing. Only after removing "Foo $foo, " from the method signature does it print "bar".

Reproduce code:
class Foo {
    public function bar(Foo $foo, $bar = 'bar') {

$class = new ReflectionClass('Foo');
$method = $class->getMethod('bar');

foreach ($method->getParameters() as $parameter) {
    if ($parameter->isDefaultValueAvailable()) {
        print $parameter->getDefaultValue();

Expected result:
