Variable parameters to variable class constructor

[comingupslowly]

Hi

I have a PHP problem I can't solve.

I'm using variable names as class constructors in a project, a la:

$foo = "ClassName" ;
$bar = new $foo();

But what I can't work out is how to pass a variable number of
parameters to the constructor; call_user_func_ array looks good, but I
don't think that'll work in the same way as 'new'.

So what I'm trying to do is:

$bar = new $foo($a, $b, $c);

Where I'm getting the parameters for the constructor from func_get_args
and as such, I don't know many parameters there are.
Any suggestions?

Thanks,

Justin

Time to use good old eval()

<?

$args = array("first", "second", "third");
extract($args, EXTR_PREFIX_ALL , "arg");
$names = array();
for($i = 0; $i < count($args); $i++) $names[] = "\$arg_$i";
$code = "new $class(" . implode(',', $names) . ")";
eval($code);

?>
