Ok, thanks for that referral.
The following code shows a bit of a simple usage of the reflectionMethod
class, on a quickly generated test class and one of it's methods:
<?php
class myClass
{
public function __init() {
}//end of __init
public function anything($sVar1 = "5") {
}//end of anything function
}//end of myClass
$className = "myClass";
$methodName = "anything";
$r = new ReflectionMethod($className, $methodName);
$params = $r->getParameters();
echo "<ul>\n";
foreach ($params as $param)
{
echo "<li><ul>\n";
echo "<li>parameter: " . $param->getName() . "</li>\n";
echo "<li>allowsNull: " . strval($param->allowsNull()) . "</li>\n";
echo "<li>optional: " . strval($param->isOptional()) . "</li>\n";
if ($param->isOptional()) { echo "<li>defaultValue: " .
$param->getDefaultValue() . "</li>\n"; }
echo "</ul></li>";
}
echo "</ul>\n";
?>

You need to take a look at reflection in the PHP manual
(http://www.php.net/manual/en/book.reflection.php). From the introduction:
"PHP 5 comes with a complete reflection API that adds the ability to
reverse-engineer classes, interfaces, functions, methods and extensions.
Additionally, the reflection API offers ways to retrieve doc comments for
functions, classes and methods."
Sounds like what you're looking for.

Subject: Determining an external function/method's
argument/parameter listing..?
If I managed to determine that a ffunction/method exists for an external
class, by finding it in the array returned by the
get_class_methods('className') function, but, then how would I determine
the
required/possible parameters for one of those functions/methods..?
Inside a function itself you can call something like func_get_args() but
that is, I think, meant to return a list of passed arguments/parameters,
and
can only be called from inside a function itself, whereas, I would like to
possibly determine what arguments/parameters a function expects/requires,
hopefully then at least being able to derive from the names what
types/values they then expect..?
In other words, would like to find some way to find out the sort of
function
definition etc.
And, yes, it would be nice to have a look at the source code am referring
to, but in this specific case, it seems like it might not be best to ask
too
many questions...<smile>
