PHP Bug Type: Feature/Change Request
Bug description: Not constant default argument
Description:
------------
When started using php 5 I tried to do something like this:
class A {
private $var;
function B($arg = $this->var) { ... }
}
Got 'unexpected T_VARIABLE' or course, but I think it would be a nice
option to add in a future releases - default arguments computed when
function is called. It could be especially useful when used inside
classes.
Probably the same as bug #6566, but if it disappeared after php3, it
certainly should be turned on again in php5
Expected result:
----------------
Compute default arguments when calling a function, that can create those
itself. It will help if you need something like:
function A ($arg = NULL) {
if($arg == NULL) $arg=$another_arg;
.....
}
