if func_get_args supports pass by reference, we could have avoid the
loop and pre-defined arg list.
Absolute! I'm not sure why there isn't some kind of way to retrieve a
reference in this manner, but I suspect it's related to knowing which
parameters were set as reference appropriate values. For instance
contrast the following:
bind_stuff( $id, $test );
Versus the following:
bind_stuff( 5, $test );
Defining the function parameters to use references will generate a fatal
error when 5 is passed since this is a fatal error. How then to enable
variable args to achieve the same result? I guess one could ask PHP to
support something like the following:
$args = func_bind_args( array( true, true ) );
Where $args would then contain a reference where the corresponding index
was set to true in the argument list. Since this isn't very variable,
then the last index set would denote the default for all other args.
Thus the example above could be shortened:
$args = func_bind_args( array( true ) );
$args = func_bind_args( true );
Since this is run-time too, then PHP could generate an E_WARNING instead
of E_FATAL and bind a copy instead when no reference was passed.
On further thought, the current func_get_args() could be adapted in this
manner since it currently accepts no arguments.
Anyways... just thoughts. I hit this problem in the past too :)
