List of PHP functions and classes

[ImOk]

In Smalltalk I can get the list of the classes, methods and global
variables by querrying a global dictionary. In addition you can get the
arguments.

I know in PHP one can get the list of globals via the $GLOBALS array.

But Is there a way to get the list of all the functions and
classes/methods (and arguments) currently loaded in PHP by using
reflection?

Thank you

PHP 5 implements reflection, although the documentation is somewhat
hidden away in the manual, under Classes and Objects.
http://uk.php.net/manual/en/language...reflection.php.

The documentation is also somewhat spartan, but with some
experimentation you should be able to get the reflection classes to work.

I tried the test according to the docs. It seems the method of
ReflectionFunction->getParameters() does not work for internal
functions although it detects the parameters. Any ideas? Is this a bug
or am i doing something wrong?

<?php
print phpversion(); // 5.1.4

function baz(ReflectionFunction $a, $b = 1, $c = null) { }

// Create an instance of Reflection_Function with the
// parameter given from the command line.
$reflect = new ReflectionFunction("baz"); // works for this one.
//$reflect = new ReflectionFunction("strncmp"); // e.g. does not work
for this function

echo $reflect;

foreach ($reflect->getParameters() as $i => $param) {
printf(
"-- Parameter #%d: %s {\n".
" Class: %s\n".
" Allows NULL: %s\n".
" Passed to by reference: %s\n".
" Is optional?: %s\n".
"}\n",
$i,
$param->getName(),
var_export($param->getClass(), 1),
var_export($param->allowsNull(), 1),
var_export($param->isPassedByReference(), 1),
$param->isOptional() ? 'yes' : 'no'
);
}

?>

Hi,

Nice to find another Smalltalker here. I guess you already have most of
your answer. Of course you still need some list of classes. With
phpPeanuts i have a classloading function that keeps such a list in a
global variable. It was meant for use with php4, to look up the
classname in original case from the lower case result php4's get_class
function gives, but i guess you can use it for other kinds of reflection
too:
function includeClass($className, $dirPath='') {
if ($dirPath && substr($dirPath, -1) != '/')
$dirPath .= '/';

$result = require_once("../classes/$dirPath"."$className.php");

if ($result)
$GLOBALS['PntIncludedClasses'][strtolower($className)] = $className;

return $result;
}
Greetings,

BTW, if you also miss the senders and implementers search, you could
take a look at this hypercode browser:

(To my regret i did still did not find time to make it an aplha download..)
