New Comment:
1. You forgot about the "protected class" mysqli_warning.
2. Then run the following program, and explain its results. I added
mysqli_stmt only for reference, so that you see the similarity:
<?
function PrintParams($classname, $methodname){
$class = new ReflectionClass($classname);
$method= $class->getMethod($methodname);
echo "$classname::$methodname():\n";
$parameters = $method->getParameters();
foreach ($parameter as $param)
{
echo "$param : ".$param->getName()." \n";
}
}
PrintParams('MySqli_stmt','bind_param');
PrintParams('SoapClient','__call');
PrintParams('SoapClient','__soapCall');
?>
3. furthermore - new reflection issues, not really related to MySqli:
a bunch of interfaces have no extension associated. For example try
php.exe --rc RecursiveIterator -you'll see that it prints
<internal:SPL> (which is probably correct). But php.exe --rc Iterator,
or php.exe --rc ArrayAccess will print only <internal>.
Coincidentally, this means that you can't find the "Iterator"
interface in any extension (e.g. using
ReflectionExtesions::GetClasses) - IMO, it should be either in "SPL"
or in "standard", but not completely "missing".

host_info and such is only there when you actually have connected
somewhere. How about you refine your report and try with an actual
object first?

I tried
http://windows.php.net/downloads/snaps/php-5.2-nts-win32-VC6-x86-
latest.zip - I get the same behaviour

Description:
------------
There are several things that go wrong with reflection on MySqli.
1. First and foremost - extracting mysqli::bind_param signature yields
strange results: public function bind_param($);
And the parameter in question (printed as "$") is in fact:
ReflectionParameter::__set_state(array(
'name' => NULL,
)) /// Null name!!
I believe this is actually related to bug #45578 - but that one has
been closed as being related to something completely different.
2. another odd thing is that reflection returns "final protected class
mysqli_warning " (and a class can't be "protected").
3. Several properties seem to be completely missing from reflection -
e.g. the "host_info" property of mysqli.
4. Parameters are not shown in member methods - e.g. mysqli::prepare
is shown to have 0 parameters (when in fact, it receives a string
parameter).
Reproduce code:
---------------
$ext = new ReflectionExtension('mysqli');
$class_arr = $ext->getClassNames();
foreach($class_arr as $cls_name){
DumpClass($cls_name);
}
// I could give the implementation of DumpClass if needed, but it's
straight out of the "reflection" examples, it prints the modifiers,
class name, "extends", "implements" & properties/methods
Expected result:
----------------
MySqli class seen through reflection the same way as it is documented
on
www.php.net
Actual result:
--------------
Wrong output from reflection (as listed in "description")
