Right.
I think this shouldn't be fixed.

Note: Because this function depends on the current scope to determine
parameter details, it may only appear in the first argument to a
function. Thus
myfunc1 (myfunc2 (func_get_arg(1), 7)) OK
myfunc1 (myfunc2 (7, func_get_arg(0))) Error
myfunc1 (7+func_get_arg(0)+func_get_arg(1)) OK
myfunc2 (func_get_arg(0), func_get_arg(1)) Error
If you must pass this value of func_get_arg() not in the first
argument, assign the results to a variable, and pass the variable."

Dmitry, this script should fail for all of those:
<?php
function doTitle($a = NULL, $b = NULL) {
print "doTitle: $a, $b\n";
}
function doHead() {
doTitle(func_num_args());
doTitle(func_get_arg(0));
doTitle(func_get_args());
}
doHead("1", "2");

Manual says:
"Note: Because this function depends on the current scope to determine
parameter details, it cannot be used as a function parameter. If you
must pass this value, assign the results to a variable, and pass the
variable."

Well, that's true then. But I'm not sure how important this bug is :)

Hi Derrick,
I don't consider to be bug, that it cannot be used as function
argument.
However I consider to be bug, that it CAN be used if you use it only
once.
This works:
doTitle(func_get_arg(0));
This works also:
doTitle(func_get_arg(1));
So it should not work at all, to be consistent.
Ondrej.
