At the moment the parser/compiler/executor trio doesn't allow this at
all. Before we can suppport this we'd need major changes all over the
engine becuase the current situation is that we allways have two
opcodes for every parameter. Allowing other things as default
parameters would break this rule....

This probably shouldnt be supported in the engine. I'm not aware of any
languages where this is supported. If you want a default value, then use
the existing capability to set it withing the scope of the function.

Description:
------------
Hey,
I've shown a function I'm trying to write that is giving me an error
because I can set an object as a default function parameter.
I don't know if this is a bug, or it wasn't intended to be possible but
I reckon it would be a good addition. I can't see a specific reason not
to have this functionality unless it runs into some issues such as
namespaces did.
Thanks :)
Reproduce code:
---------------
public function PadLeft ( Int32 $var1, Char $var2 = new Char ( ' ' ) )
{ // line 315
try {
$this->Value = str_pad($this->Value, $var1->Value, $var2->ToString(),
STR_PAD_LEFT);
return( true );
} catch ( xException $ex ) {
return( $ex->False );
}
}
Expected result:
----------------
I wasn't expecting to see the error anyway :p
I'd like to have the result I'm looking for returned if possible.
Actual result:
--------------
Parse error: parse error, unexpected T_NEW in
D:\www\root\objects\TMP2ct7ths5f1.php on line 315
