Hi all,

Referring to call_user_func_array() I would like to suggest a new
function: new_object_array().
I'm working on a php5 application framework and I would like to
implement something I call an unified factory. The problem is that I
don't know how many parameters to expect.

Here's an example how it's meant to work:
<?PHP
class Kernel
{
public function __call($functionName, $functionParameters)
{
$className = substr($functionName, 3);
// code omitted here ...
// check for real $className ...
return new_object_array($className, $functionParameters);
}

public function newObject()
{
$functionParameters = func_get_args();
$className = array_shift($functionParameters);
// code omitted here ...
// check for real $className ...
return new_object_array($className, $functionParameters);
}
}

$Kernel = Kernel::getInstance();
$DbManager = $Kernel->getDbManager('param1', 'param2'); // 1st
possibility to get new object
$XmlParser = $Kernel->newObject('XmlParser', 'param1', 'param2'); // 2nd
possibility to get new object
?>

I have written an implementation of new_object_array(); <-- see attachment
Perhaps some things need to be rewritten ;)

I would be happy if you would consider to include this function in the
standard distribution of  php.

Yours sincerly,
Julian Reich

How about:

return call_user_func_array(
array(new ReflectionClass($className), 'newInstance'),
$functionParameters
);

Untested but should work.

Yep, I have done something similar and it worked. The Reflection API is quite powerful.

I also considered this possibility, but it looked like big overhead.
Am I wrong?

I agree that it's best to keep this in user-land using the existing
reflection API.

Hello Julian,

adding a new function seens the wron way. I'd prefer adding this
functionality to the reflection API. Hande a look at
Zend/zend_reflection_api.c: ZEND_METHOD(reflection_class, newInstance)
